Question 5

f(x)=x3+4x2+x−6.f(x) = x^3 + 4x^2 + x - 6.f(x)=x3+4x2+x−6.

a.

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

[2]
b.

Factorise f(x)f(x)f(x) completely.

[4]
c.

Write down all the solutions to the equation

x3+4x2+x−6=0. x^3 + 4x^2 + x - 6 = 0. x3+4x2+x−6=0.
