Step 1

We check for few xs by plugging them in the given function

Of those values x=3 gives g(3)=0

This means (x-3) is a factor of the equation.

Step 2

Then we divide the function by x=3 using synthetic division.

Quotient = 2x^2+11x+5

Step 3

Then we try to find x from 2x^2+11x+5 =0 by factoring.

x= -5 , -1/2
