WebHow To: Given a factor and a third-degree polynomial, use the Factor Theorem to factor the polynomial Use synthetic division to divide the polynomial by [latex]\left(x-k\right)[/latex]. Confirm that the remainder is 0. Write the polynomial as the product of [latex]\left(x-k\right)[/latex] and the quadratic quotient. WebDivide the polynomial by x-2 to (x 2 – 4x + 3) = 0. Now solve the quadratic equation (x 2 – 4x + 3) = 0 to get x= 1 or x = 3 Therefore, the solutions are x = 2, x= 1 and x =3. Example 6 Solve the cubic equation x 3 – 7x 2 + 4x + 12 = 0 Solution Let f (x) = x 3 – 7x 2 + 4x + 12 Since d = 12, the possible values are 1, 2, 3, 4, 6 and 12.
