Question

Q. 1 Find the value of a if x + 6 is a factor of x3 + 3x2 + 4x + a.

Answer 1

Answer:

x+6=0

x= -6

p(x)=x^3+3x^2+4x+a

p(-6)= (-6)^3+3(-6)^2+4(-6)+a=0

Therefore,

= -216+108-24+a=0

= -240+108+a=0

= -132+a=0

=a= +132

Hope my answer helps you :)

Answer 2

Answer:

Step-by-step explanation:We need to apply the Factor Theorem here.

We solve for the x of the g(x)
