Answer:

Step-by-step explanation:

4(3a-3)+2a when you expand youget

((4x3a)-(4x3)) + 2a = 12a - 12 + 2a then we collect the like term first 12a + 2a - 12

14a -12

therefore 14a - 12 is not equal to 14a- 3

12a-12+2a = 14a-3
14a-12 = 14a-3

So he’s not correct.

Answer:

(4x - 3)(3x² + 1)

Step-by-step explanation:

Given

12x³ - 9x² + 4x - 3 ( factor the first/second and third/fourth terms )

= 3x²(4x - 3) + 1(4x - 3) ← factor out (4x - 3) from each term

= (4x - 3)(3x² + 1) ← in factored form
