Question

Let f(x) = 4x3 + 7x2 – 13x – 3 and g(x) = x + 3. Find f of x over g of x

Answer 1

put x = -3 in f....check whether it s 0

Answer 2

4x3 + 7x2 – 13x – 3 / x + 3
now what do I do next?

Answer 3

noo put....check if f(-3)=0

Answer 4

but this is synthetic division..

Answer 5

yea.......

Answer 6

It is not a factor and a remainder exists, just complete the division getting
4x^2-5x+2 with a remainder of -9 (-9)/(x+3)
