In one sentence, describe what the following article is about: The denominator will be the number in the problem you are dividing by. A binomial is a two-termed polynomial. This method only applies to division of square roots involving a binomial. For example, if you are calculating 15+2{\displaystyle {
rac {1}{5+{\sqrt {2}}}}}, you have a binomial in the denominator, since 5+2{\displaystyle 5+{\sqrt {2}}} is a two-termed polynomial. Conjugate pairs are binomials that have the same terms, but opposite operations. Using a conjugate pair will allow you to cancel the square root in the denominator. For example, 5+2{\displaystyle 5+{\sqrt {2}}} and 52{\displaystyle 5-{\sqrt {2}}} are conjugate pairs, since they have the same terms but opposite operations. Doing this will allow you to cancel the square root, because the product of a conjugate pair is the difference of the square of each term in the binomial. That is, (ab)(a+b)=a2b2{\displaystyle (a-b)(a+b)=a^{2}-b^{2}}. For example:15+2{\displaystyle {
rac {1}{5+{\sqrt {2}}}}}=1(52)(5+2)(52){\displaystyle ={
rac {1(5-{\sqrt {2}})}{(5+{\sqrt {2}})(5-{\sqrt {2}})}}}=52(52(2)2{\displaystyle ={
rac {5-{\sqrt {2}}}{(5^{2}-({\sqrt {2}})^{2}}}}=52252{\displaystyle ={
rac {5-{\sqrt {2}}}{25-2}}}=5223{\displaystyle ={
rac {5-{\sqrt {2}}}{23}}}Thus, 15+2=5223{\displaystyle {
rac {1}{5+{\sqrt {2}}}}={
rac {5-{\sqrt {2}}}{23}}}.
Summary: Determine that you have a binomial in the denominator. Find the conjugate of the binomial. Multiply the numerator and denominator by the denominator's conjugate.

In one sentence, describe what the following article is about: Animal tracks are more visible at these times of day, when the slant of the light makes it easier to see the shadows made by tracks. Tracking when the sun is high in the sky is a lot harder. In addition, many animals are more active in the morning and evening than they are in the middle of the day. Getting close to the ground and looking at the tracks sideways can also help you see the tiny indents and ridges that indicate an animal walked over a certain spot. Start where you can clearly see tracks. The easiest way to start tracking an animal is to begin in a spot where you see undeniable tracks, like in freshly fallen snow or in a muddy spot. From there, you can follow the tracks to areas where they're not quite as easy to detect. Experienced trackers use their sense of touch as much as their sense of sight to figure out which way an animal went. Try tracking while blindfolded to get an even deeper understanding of the animal. Feel the animal's prints and search along the ground with your hands until you find more. Follow them until you understand the way the animal moved through the forest or meadow.
Summary: Track in early morning or late afternoon or early evening. Use your hands to see.

In one sentence, describe what the following article is about: Pour the boiling water in and stir until the sugar is completely dissolved. Set the container aside and allow it to cool down. Place it into the freezer for about 2 hours. Take off the wrapping and use a fork to break up the coffee mixture. Put back the wrapping and re-freeze the container for another 30 minutes. Use a fork to break up any big chunks and achieve a flaky texture. Top the drink off with whipped cream and enjoy!
Summary:
Get a bowl and combine the sugar and coffee grounds. Place the sieve over the container and strain the mixture. Use plastic wrap to cover the container. Remove it from the freezer after the 2 hours. Mash it until you get more of a "slushie" iced mixture. Remove the container from the freezer and throw away the plastic wrapping. Use a spoon to serve the granita into glasses.
