Question

The three roots of the equation f(x) = 0 are x = {2, 0, 3}. What are the three values of x for which f(x 3) = 0?

Answer 1

We can then solve the quadratic equation by using the formula for solving quadratics. ... We can easily use the same method to solve a fourth degree equation or equations of a still higher degree. Solve the equation f(x) = x4 − x3 − 5x2 + 3x + 2 = 0. First we find the integer factors of the constant term, 2.
