Answer:
a = 4 and b = - 30
Step-by-step explanation:
Expand the left side and compare like terms on both sides, that is
(x + 2)(x - 3)(x + 5) ← expand the first pair of factors using FOIL
= (x² - x - 6)(x + 5) ← distribute
= x³ + 5x² - x² - 5x - 6x - 30 ← collect like terms
= x³ + 4x² - 11x - 30
Compare like terms with x³ +ax² - 11x + b
4x² and ax² ⇒ a = 4
+ b and - 30 ⇒ b = - 30
Could you past the graphs. I would like to help:)
F(-5) = 2(-5) + 1 = -9
g(-5) = (-5)^2 = 25
(f*g)(-5) = -9(25) = -225
3x+17=2x-6
-2x -2x * subtract 2x from both sides* *3x-2x is 1x*
1x+17=-6 *now subtract 17 from both sides*
-17 -17
1x=-23
1x. 1x
x=23
