Devon decided to rewrite the quadratic equation so that it could be simplified into a square in order to find the zeros.
which process correctly shows devon rewriting x2 +10x+13 into a square?
a) (x2 + 10x + 25) + 13(x + 5)2 +13
b) (x2 + 10x + 25) + 13 - 25(x + 5)2 -12
c) (x2 + 10x + 100) + 13 - 100(x + 10)2 -87
d) x = 10 ± 102 - 4(1)(13)2
