This is josh’s solution for the equation x^2-6x-7=0:
x^2-6x-7=0
x^2-6x=7
x^2-6x+9=7+9
(x-3)^2=16
x-3=+/-4
x=-3+/-4

x=-3+4 x=-3-4
x=1 x=-7

is josh’s solution correct? explain

answer: yes youre right.

step-by-step explanation:

27 + 13x + 15 = (x + 5)( =

step-by-step explanation:

27 + 13x + 15 = (x + 5)( = 27 + 13x + 15 = (x + 5)( = 27 + 13x + 15 = (x + 5)( =
