What is 12x3 – 9x2 – 4x + 3 in factored form?

(3x^2 + 1) (4x – 3)
 12x^3 – 9x^2 + 4x – 3 in factored terms;
3x^2 is a common factor in 12x^3 and 9x^2
 Pulling out 3x^2, we have 3x^2 (4x – 3) + 4x – 3
 Splitting the expression into 2 groups (3x^2 (4x – 3) and 4x – 3)
4x – 3 is a common factor in both groups
 Factorizing 4x – 3, we have 3x^2 (4x – 3) + 1 (4x – 3)
Therefore, in factored form, the equation becomes (3x^2 + 1) (4x – 3)
