g(x)=4x3−8x2−35x+75g(x) = 4x^3 - 8x^2 - 35x + 75g(x)=4x3−8x2−35x+75

a.

Use the factor theorem to show that (x+3)(x + 3)(x+3) is a factor of g(x)g(x)g(x)

[2]
b.

Hence show that g(x)g(x)g(x) can be written in the form g(x)=(x+3)(ax+b)2g(x) = (x + 3)(ax + b)^2g(x)=(x+3)(ax+b)2, where a a\,a and b b\,b are constants to be found.
