Question

6. Use the remainder theorem to find P(-3) for P(x) = x³+4x²+4

Answer 1

STEP - BY - STEP EXPLANATION

Given:

$P(x)=x^3+4x^2+4$

Step 1

Suppose x= -3, then

x+ 3

Step 2

Divide the polynomial by (x+ 3)

Step 3

Determine the remainder and quotient from the above.

Quotient = x²+ x - 3

Remainder = 13

ANSWER

Quotient = x²+ x - 3

Remainder = 13
