Answer:
a² + b²
Step-by-step explanation:
(a + b)² - 2ab ← expand parenthesis using FOIL
= a² + 2ab + b² - 2ab ← collect like terms
= a² + b²
Given: f(x)=(2x-2)/4
find f^-1(3)?
we need to find the inverse of f(x), so
x=(2y-2)/4
2y-2=4x
y-1=2x
y=2x+1
so, then f^-1(x)=2x+1
f^-1(3)=2(3)+1
=6+1
=7
so, the answer is 7
Answer:
x to the third power is x cubed or x^3.
Answer:
2x^2+16x-66
Step-by-step explanation:
Use FOIL (First, Outside, Inside, Last)
(2x-6)(x+11)
F- 2x*x=2x^2
O-2x*11=22x
I--6*x=-6x
L--6*11=-66
2x^2+22x-6x-66
Combine like terms
2x^2+16x-66
