Question

A) If the result of a division problem is written as x^3+2x^2+3x-4=(x^2+3x+6)(x-1)+2, identify the dividend, quotient, divisor, and remainder. What do you know about the function at (x=1)

B) When the polynomial P(x)=3x^3+22x^2+38x+15

 is divided by (x+2) , the remainder is 3 . What is known about the function? 

C)If P(-5)=0, what is known about the function

Answer 1

The dividend is on the left, the quotient is the quadratic, the divisor is (x-1) and the remainder is 2.

The rest of the answers can be learned from the form

P(x) = Q(x)(x-r) + R(x)

Look what happens in this equation when you substitute x=r!
