Factor out the common factor 4x:
4x^3 - 32x^2 + 28x = 4x(x^2 - 8x + 7).
Factor the quadratic:
x^2 - 8x + 7 = (x - 1)(x - 7).
So the full factorization is
4x^3 - 32x^2 + 28x = 4x(x - 1)(x - 7),
with roots x = 0, 1, 7.
4x^3 - 32x^2 + 28x = 4x(x^2 - 8x + 7).
Factor the quadratic:
x^2 - 8x + 7 = (x - 1)(x - 7).
So the full factorization is
4x^3 - 32x^2 + 28x = 4x(x - 1)(x - 7),
with roots x = 0, 1, 7.
