Step 1
Given;

Required; To Use long division to rewrite ((x) in factored form and find all zeros.
Then sketch the graph.
Step 2
Rewrite ((x) in factored form. one of the zeroes of f(x) is x=3

Hence will divide by a factor of (x-3) and then (x+2)
Step 3
Factorize -x²+3x

Therefore all the zeroes are;
