Answer:
x^3 + 10x^2 + 21x - 12
Step-by-step explanation:
(x + 4)(x^2 + 6x - 3)
you can separate to make it easier for u
x(x^2 + 6x - 3) + 4(x^2 + 6x - 3), this is optional u don't have to do this part
x^3 + 6x^2 - 3x + 4x^2 + 24x - 12
add like terms together
x^3 + 10x^2 + 21x - 12

Answer:
2x^2 + 7x.
Step-by-step explanation:
8x^2 - 5x + 3x(4 - 2x)
= 8x^2 - 5x + 12x - 6x^2
= 2x^2 + 7x.
Answer:
A
Step-by-step explanation:
You literally just have to use a calc or solve it by yourself. Doesn't need a graph.
-2x + 3 = 3x - 2 (-3 and -x create positive)
-5x + 3 = -2 (subtract 3x from both sides)
-5x = -5
x= 1
