# How To 9 2 practice solving quadratic equations by graphing answer key: 4 Strategies That Work

The 25/4 and 7 is the result of completing the square method. To factor the equation, you need to first follow this equation: x^ 2 + 2ax + a^2. In x^2 +5x = 3/4, The a^2 is missing. To figure out the a, you need to take the 5 and divide it by 2 (because 2ax), which becomes 5/2. a=5/2. Then you need to square it, (because a^2) which becomes 5^2/2^2.

Mr. Kramer's Math Website - Home Because of that, if we are solving x² = 9, we have to allow for either correct answer. So we say, x = ± 3 and that means that x = 3 or x = -3. When we have the more complicated case of x² = 13. the square root will be x = ± √13 and that means we have two possible answers: x = +√13 and x = - √13.Mid-Chapter Quiz.
