Move all of the terms to one side of the equal sign, keeping the x2{\displaystyle x^{2}} term positive. Write the terms in descending order of degrees, so that the x2{\displaystyle x^{2}} term comes first, followed by the x{\displaystyle x} term and the constant term. Here's how you do it: 4x2 - 5x - 13 = x2 -5 4x2 - x2 - 5x - 13 +5 = 0 3x2 - 5x - 8 = 0 The quadratic formula is: bb24ac2a{\displaystyle {
rac {-b\pm {\sqrt {b^{2}-4ac}}}{2a}}} The variable a is the coefficient of the x2 term, b is the coefficient of the x term, and c is the constant. For the equation 3x2 -5x - 8 = 0, a = 3, b = -5, and c = -8. Write this down. Now that you know the values of the three variables, you can just plug them into the equation like this: {-b +/- (b2 - 4ac)}/2 {-(-5) +/- ((-5)2 - 4(3)(-8))}/2(3) = {-(-5) +/- ((-5)2 - (-96))}/2(3) After you've plugged in the numbers, do the remaining math to simplify positive or negative signs, multiply, or square the remaining terms. Here's how you do it: {-(-5) +/- ((-5)2 - (-96))}/2(3) = {5 +/-(25 + 96)}/6 {5 +/-(121)}/6 If the number under the radical symbol is a perfect square, you will get a whole number. If the number is not a perfect square, then simplify to its simplest radical version. If the number is negative, and you're sure it's supposed to be negative, then the roots will be complex. In this example, (121) = 11. You can write that x = (5 +/- 11)/6. If you've eliminated the square root symbol, then you can keep going until you've found the positive and negative results for x. Now that you have (5 +/- 11)/6, you can write two options: (5 + 11)/6 (5 - 11)/6 Just do the math: (5 + 11)/6 = 16/6 (5-11)/6 = -6/6 To simplify each answer, just divide them by the largest number that is evenly divisible into both numbers. Divide the first fraction by 2, and divide the second by 6, and you have solved for x. 16/6 = 8/3 -6/6 = -1 x = (-1, 8/3)

Your light meal could include plain butter cookies, plain pound cake, or small rice crackers. Green tea goes well with sweet foods, as the tea is more bitter than the food, and will moderate the sweet taste of the food. Mochi is a Japanese glutinous rice cake that is usually circular in shape and dyed different colors. Mochi is available in savory and sweet flavors. The sweet version is known as Daifuku, which are round glutinous rice balls filled with sweet ingredients like red bean or white bean paste.

You can meditate any time, anywhere, but for most beginners, it's significantly easier to meditate in a quiet place with no distractions. Try to find somewhere where you can be alone for a few minutes. You may want to set up a special area in your home for meditation. It should have a comfortable place for sitting and should be inspiring to you. You can create an altar or shrine, or simply decorate the area with items that speak to you. Do your best to have good posture while meditating. Sitting up straight is not only good for your spine, but it may also help you stay focused on your meditation. Sitting on a pillow or block may help you keep your spine straight. Beginning a meditation practice does not have to take much time away from your busy schedule. You can start by devoting as little as 10 minutes each day to meditation. Scheduling a regular time to meditate each day may help you commit to it. As you progress, you may find that you want to meditate for longer periods of time, but if you don't, that's okay too. Never feel like you have to meditate for a specific amount of time if that doesn't feel right for you. Some people find it helpful to spend the beginning of their meditation session thinking about a specific intention. This should be something altruistic that will help you stay focused on the good that you are creating with your meditation practice. For example, you may think about how your meditation will help you be present in the current moment and not ruminating on the past or worrying about the future. Journaling about the meditation process is very useful to some people, so you may want to consider trying it. This will allow you to keep track of the different meditation techniques you have tried and how they made you feel. In addition, journaling can also help you work through your feelings, so you may find that it helps you understand why a specific technique made you feel a specific way.
