Answer:
Step-by-step explanation:
First, distribute,
12(-2x+3)-3x+9(x-9)
-24x+36-3x+9x-81
Now combine like terms,
Therefore, the answer is -18x-45
- 18x - 45
= 12 (-2x + 3) - 3x + 9 (x - 9)
= -24x + 36 - 3x + 9 (x - 9)
= -24x + 36 - 3x + 9x - 81
= -24x + 8x + 36 - 81
= - 18x - 45

a = 1
b = 9
c = 23
d = 15
Expand it out:
(x^2 + 4x + 3)(x+5)
(x^3 +4x^2 +3x + 5x^2 + 20x + 15)
=x^3 + 9x^2 + 23x +15
