Question

Help please, question below, show how to do too!

Answer 1

You can use two methods to find the answer

First(by using function):
Let f(x)=2x^3+3x^2-4x+k
Replace x by -2 since (x+2) is a factor of f(x)

f(-2)=2(-2)^3+3(-2)^2-4(-2)+k=3 (Since the remainder is 3 when divided by (x+2))
You can work it out

Second (by using long division method):
Same result but can be quite long

I would choose the first method if I were you. ;)
