2x^2+5x+17

your welcome. : )

in total they made   333.74 your welcome : d

answer: i think its red because you have to see what it equals to

hope that

josh is incorrect

x= 7 and x= -1

step 2 is wrong and honestly first step is not needed, you just need to figure out the factors

i know its wrong because if you plug in the solutions josh found, they do not work (in the original equation)

x^2 -6x -7 = 0

(x-7) (x+1) = 0

x-7=0 x+1=0

x= 7 x= -1
