1 answer:
X^2 + 6x = 13. We are to "complete the square."
x^2 + 6x + (6/2)^2 - (6/2)^2 = 13
Then (x+3)^2 - 9 = 13, or (x+3)^2 = 22.
then x+3 = plus or minus sqrt(22), or x = -3 plus or minus sqrt(22).
Given x^2 + 6x = 13, to complete the square we insert " 3^2 - 3^2 " between the "6x" and the "=" sign.
