X cannot equal +2, and can't be -1. If you factor it, then you notice you get 2(x+2)(x-2). If you use either one for the x, one will be zero and the won't, and vise-versa.

Answer:
Step-by-step explanation:
55*4^(33/11) = 55*4^3 = 55*64 = 3520
Answer:
x=4
y=1
Step-by-step explanation:
4x=7y+9
4x+y=17
7y+9+y=17
8y=17-9
8y=8
y=1
so
4x=7*1+9
4x=16
x=16/4
x=4
Rewrite using the formula for the standard form
The answer is y-4x^2 + 12x + 9
