Question

check whether the first polynomial is a factor of the second polynomial by dividing the second polynomial by the first polynomial x+8,x^3+15x^2+56x​

Answer 1

Answer:

FIRST OF ALL, LET ME TELL YOU THAT THE FIRST POLYNOMIAL IS THE FACTOR OF THE SECOND POLYNOMIAL....

YOU CAN SIMPLY FIND THE ANSWER BY LONG DIVISION METHOD

   OR YOU CAN APPLY THE METHOD GIVEN BELOW......

We know that,

x= -8

putting the value of x in the second polynomial given, we get:

=> (-8)^3 + 15(-8)^2 + 56(-8) = (-512) + 15(64) - 448

=>  -512 + 960 - 448 = 448 - 448 = 0

THIS IS THE REQUIRED ANSWER
