Question

Answer fast!!! Its urgent !! plzzz!!
For what value of m is x^3-2m^2+16 is divisible by x+2?

Answer 1

Hi !!!

This is your answer.

Given :- x³ -2m² +16
One factor = x +2.
As, x +2 = 0.
So, x = -2.

Hence, zero of given polynomial is -2.
We know that zero of polynomial is that value of x which makes the whole polynomial equal to zero.

So, putting value of zero in polynomial....

(-2)³- 2m² +16
-8 - 2m² = -16
-2m² = -16 +8
-2m² = -8
m² = -8/-2
m² = 4
m = 2.

Hence. the value of m that make is divisible by X+2 is 2.

Hope you got the answer
