Question

2. Evaluate the polynomial two ways: by substituting in the given

value of x, and by using long division.
Find P(-3)for P(x)= 4x2 +10x - 8.

Answer 1

P(-3) = -2 i think that’s what it’s keeps giving me

Answer 2

P(-3) = -2

Explanation:

Substitution

P(-3) = 4(-3)^2 +10(-3) -8 = 36 -30 -8

P(-3) = -2

__

Long Division

See the working below. The remainder is -2, so ...

P(-3) = -2
