Factor 3x^2 + 9x + 6.

Explanation:
Pull out the greatest common factor. All three terms share a 3, so you can factor it out: 3(x^2 + 3x + 2). This shows the expression in a simpler, factored-with-respect-to-a-factor form. The inner quadratic can further be broken down as x^2 + 3x + 2 = (x + 1)(x + 2), giving the fully factored form 3(x + 1)(x + 2). The other forms don’t reflect this factoring step or, in some cases, change the middle and constant terms, so they aren’t the clean representation of the factoring process.
