Y x y = y^2
-9 x y = -9y
-2 x y = -2y
-9 x - 2 = 18
y^2 -9y -2y + 18
y^2 -11y + 18
(^2 = squared)
Answer:
quick fyi! i dont recommend clicking on links there probably fake.
Answer:
f(x) = x + 3y = x + 3x = y - 3Inverse is h(x) = x - 3
Difference of two squares:
x² - y² = (x - y)(x + 8)
So for difference of squares that has (x -8) as one of the factor.
The other factor is (x + 8)
(x - 8)(x + 8) = x² - 8²
= x² - 64.
