5) which one of the equations has a graph with no x-intercepts? a) y = 4x b) y = -x2 c) y = x2 - 1 d) y = -x2 - 1 6) 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
In order to finish completing the square you need to half the coefficient in front of x, square it and add and subtract it in order to not change the value of the expression.
(x2 + 10x + 25) + 13 - 25
(x + 5)2 -12
