Hello!
8u - 8 = -7(u - 1) Given
8u - 8 = -7u + 7 Apply Distributive Property
15u - 8 = 7 Add 7u to both sides
15u = 15 Add 8 to both sides
u = 1 Divide both sides by 15
Answer:
u = 1
Hope this helps!
No, it is not.
If x+1 is a factor, x=-1 would be one of the zeros.
Plug x=-1 in the polynomial to see it is results in a 0:
2(-1)^3-9(-1)^2+13(-1)-6=-30≠0, therefore, x+1 is not a factor.
