Question

13. Check whether x+2 is a factor of x³+2x²+3x+6.​

Answer 1

Given p(x)=x

3

+2x

2

+3x+6 and g(x)=x+2

Then g(x)=0 so x=−2 replace x by −2 we get

p(−2)=(−2)

3

+2(−2)

2

+3(−2)+6

p(−2)=−8+8−6+6

p(−2)=0

So remainder is zero then x+2 is factor of x

3

+2x

2

+3x+6

Answer 2

Answer:

X=-2

Explanation:

because when we place -2 in x place the entire becomes zero
