Question

Express 9x3 + 6x2 – 3x in factored form. 3x(x – 1)(3x – 1) 3x(x – 1)(3x + 1) 3x(x + 1)(3x + 1) 3x(x + 1)(3x – 1)

Answer 1

Start by factoring out the GCF, which is 3x:

3x(3x^2 + 2x - 1). Then factor the trinomial 3x^2 + 2x -1:

3x(3x-1)(x+1):

Answer 2

Start by factoring out the GCF, which is 3x:

3x(3x^2 + 2x - 1). Then factor the trinomial 3x^2 + 2x -1:

3x(3x-1)(x+1)
