Question 4

f(x)=2x3−x2−13x+14f(x)=2x^3-x^2-13x+14f(x)=2x3−x2−13x+14

a.

Use the factor theorem to show that (x−2)(x-2)(x−2) is a factor of f(x)f(x)f(x).

b.

Hence, or otherwise, solve the equation 2x3−x2−13x+14=02x^3-x^2-13x+14=02x3−x2−13x+14=0, giving your answers to 2 decimal places where appropriate.
