Question

Find the remainder when x³+3x²+5x+6 divisible by 2x+4 and specify is it factor of taht polynomial ? ​

Answer 1

Step-by-step explanation:

p(x)=x3−3x2+5x+7

Remainder =p(3)=(3)3−3(3)2+5(3)+7=27−27+15+7=22

For (x−3) to be a factor, p(3) must be equal to zero.

Here, p(2)=0.

Hence, (x−3) is not a factor of this polynomial.
