If x²-1 is a factor of the polynomial, both x-1 and x+1 are factors of it.
According to the remainder theorem, if a binomial x-a is a factor of a polynomial p(x), then p(a)=0.
If x-1 and x+1 are factors of the polynomial p(x)=ax⁴+bx³+cx²+dx+e, then p(1)=0 and p(-1)=0.
Answer:
A, B, D, G, and F
Step-by-step explanation:
Answer:
-20
Step-by-step explanation:
48 divided by -3 is -16 but you round up since its high enough and it goes to -20
I think its -18
Step-by-step explanation:
-2/9 = 4 /m
-2 <u>×</u><u>-2</u> = 4
so you would do the same to the bottom
9 <u>×</u><u>-2</u> = -18
sorry if I'm wrong
