Answer:

There is a number added to the quadratic equation that makes it a square. A quadratic equation is a parabola and for the most part, by completing the square you are finding the x intercepts.

Step-by-step explanation:

^2 +8x -20 = 0

so you have x^2 + 8x +______ = 20 + ________ the number that completes the square is the middle term 8/2 and then square that amount;16. you add 16 to both sides and you get x^2 +8x +16 = 36

(x+4)^2 =36 take the square of both sides

X+4 = +/- 6, so x+10 = 0 and x-2 = 0 x = -10 and x =2
