Quadratic is in the form
ax^2+bx+c=0
so distribute and stuff and simplify
remember
a(b+c)=ab+ac
(x+2)^2+5(x+2)-6=0
remember order of opertaions
(x+2)(x+2)+5(x+2)-6=0
x^2+4x+4+5x+10-6=0
add like terms
x^2+9x+8=0
Answer:
y=2x-23
Step-by-step explanation:
m=(-9+7)/(7-8)=-2/-1=2
y=2x+b
-7=2(8)+b
-7-16=b
b=-23
y=2x-23
