Answer:
x = -3/2, -2
Step-by-step explanation:
2x^2 + 7x + 6 = 0
(2x + 3)(x + 2) = 0
(2x + 3)
2x = -3
x = -3/2
(x + 2)
x = -2
12. On addition, you can just combine like terms.
2v^3+(-v^3)=v^3
-v+v cancels each other out
8+(-3)=5
So you have v^3+5
14 On subtraction, you have to remember to distribute the negative sign so after you do that you have:
4h^3+3h+1+5h^3-6h+2
Then you can combine like terms
4h^3+5h^3=9h^3
3h-6h=-3h
1+2=3
So you end up with:
9h^3-3h+3
