Question

find the value of k if X+2 is a factor of x³+3x²+5x-k,using factor theorem​

Answer 1

Answer:

hey frnd here is your answer

Step-by-step explanation:

Given- (x+2) is a factor of x³+3x²+5x-k.

If (x+2) is factor of Polynomial then it should satisfy it.

So just put x= -2 in Polynomial.

• x³+3x²+5x-k=0

• (-2)³+3(-2)²+5(-2)-k=0

• -8+3(4)-10-k=0

• -8+12-10=k

• k= -6

so your final answer is-

k= -6.

I hope you get the right answer
