Hold your cat on your lap in the room where you keep the guinea pig. Have the room to the door closed, and allow the guinea pig to roam around the room outside of its enclosure. Wait until the guinea pig approaches and assure the cat with affectionate petting if it remains calm. It they can noses one another and remain calm, they are likely ready for supervised playtime. The room with the guinea pig enclosure is best, as the guinea pig can return to its own space if it wants to do so. Always maintain active and vigilant supervision. Don't ever allow the cat to enter the guinea pig's enclosure. Interrupt your pets' interactions if the cat begins to stalk the guinea pig or either animal begins to get agitated or aggressive. Try again another day. If aggressive behavior continues, spend time holding the cat in your lap while the guinea pig roams. Make sure they are both in the respective zones where the other is never allowed. This will allow each to feel most comfortable while you're away, and minimize the risk of coming home to blood-speckled walls. Even if they become great friends, don't ever leave them alone together.

One-sentence summary -- Let your guinea pig roam. Allow the cat and guinea pig to get to know one another. When you aren't in the house, keep the guinea pigs and cats separate.

If a person is unconscious, try to rouse them by speaking to them or by tapping at the shoulder. do not be afraid to speak loudly or even shout. If they do not respond to activity, sound, touch, or other stimulation, determine whether they are breathing. If unconscious and unable to be roused, check for breathing: look for a rise in the chest area; listen for the sound of air coming in and out; feel for air using the side of your face. If no signs of breathing are apparent, place two fingers under the chin and gently guide the face pointing upwards to open up their airways. If any debris such as vomit can be seen, it is appropriate to move them onto their side to allow it to get out, which is achieved with the recovery position. Check for a pulse. Unless you suspect a spinal injury, carefully roll them onto their back and open their airway. If you suspect a spinal injury, leave the person where they are, provided they are breathing. Keep the head and neck aligned. Carefully roll them onto their back while holding their head. Open the airway by lifting the chin. In the center of the chest, just below an imaginary line running between the nipples, put your two hands together and compress the chest down approximately 2 inches (5.1cm) at a rate of 100 compressions per minute (or to the beat of "Staying Alive"). After 30 compressions, give two rescue breaths, done by opening the airways, closing the nose and fully covering the mouth hole. Then check vitals. If the breaths are blocked, reposition the airway. Make sure the head is tilted slightly back and the tongue is not obstructing it. Continue this cycle of 30 chest compressions and two rescue breaths until someone else relieves you. The ABCs of CPR refer to the three critical things you need to look for.Check these three things frequently as you give the person first aid CPR. Airway. Does the person have an unobstructed airway? Breathing. Is the person breathing? Circulation. Does the person show a pulse at major pulse points (wrist, carotid artery, groin)? Drape a towel or a blanket over the person if you have one; if you don't, remove some of your own clothing (such as your coat or jacket) and use it as a cover until medical help arrives. However, if the person has a heatstroke, do not cover him or keep him warm. Instead try to cool him by fanning him and damping him. As you administer first aid, be sure to be aware of these things that you should not do in any case: Do not feed or hydrate an unconscious person. This could cause choking and possible asphyxiation. Do not leave the person alone. Unless you absolutely need to signal or call for help, stay with the person at all times. Do not prop up an unconscious person's head with a pillow. Do not slap or splash with water an unconscious person's face. These are movie gimmicks. If the person appears in danger due to an electric shock, you may attempt to move it, but only with a non-conductive object.

One-sentence summary -- Determine responsiveness. Check for breathing and a pulse. If the person remains unresponsive, prep for CPR. Perform 30 chest compressions and two rescue breaths as part of CPR. Remember your ABCs of CPR. Make sure the person is warm as you wait for medical help. Pay attention to a list of don'ts.

After you have eliminated all the radicals from the problem, move all the terms to one side of the equation and combine like terms. Returning to the working sample problem, this looks as follows: x1=x214x+49{\displaystyle x-1=x^{2}-14x+49} 0=x215x+50{\displaystyle 0=x^{2}-15x+50} In most cases, this step will create a quadratic polynomial. This is an equation that contains an x2{\displaystyle x^{2}} term as its highest variable. If the original radical was something other than a square root (such as a cube root or fourth root, for example), then you may have a more difficult problem. We will focus on the quadratic for this article. You may be able to solve the quadratic equation by factoring, or you can go directly to the quadratic formula. In this case, the sample problem, 0=x215x+50{\displaystyle 0=x^{2}-15x+50}, can be factored into the two binomial factors of (x5){\displaystyle (x-5)} and (x10){\displaystyle (x-10)}. Factoring the quadratic equation in this case suggests two possible solutions. Because the quadratic equation is equal to 0, you find the solutions by setting each factor equal to 0 and then solve. In the working problem, the two factors are (x5){\displaystyle (x-5)} and (x10){\displaystyle (x-10)}. Set each of these equal to 0 to get the solutions x=5{\displaystyle x=5} and x=10{\displaystyle x=10}. With another problem, you may not be able to factor and would then have to use the quadratic formula to find the solution.
