Question

(12 X^4+5X^3+3X^2-5) (X+1) What is the number you should use for the divisor in this division problem

Answer 1

What is the number you should use for the divisor in this division problem?

Set up the synthetic division problem by transferring the coefficients from the dividend into a division table.

Carry out the division and write your answer as QUOTIANT+ REMAINDER/DIVISOR

Is a factor of the polynomial ? Explain your answer

Answer 2

when dividing by (x-c) you can use synthetic division where "c" is the divisor
you have (x+1) --> c = -1

set up synthetic division

-1 | 12 5 3 0 -5
