For the function f(x) = x^3 - 2x^2 -11x +12: a) find f(0), f(1) and f(2). B) day which of (x-1) and (x-2) is a factor of f(x). C) fully factorise, and hence solve the equation f(x) =0

example 2 – simplify: step 1: completely factor both the numerators and denominators of all fractions. step 2: change the division sign to a multiplication sign and flip (or reciprocate) the fraction after the division sign; essential you need to multiply by the reciprocal. step 3 : cancel or reduce the fractions.
