lapo4ka [179]

Answer:

6x^3  - 2x^2  -11x +4

Step-by-step explanation:

(3x-4)(2x^2+2x-1)

Multiply 3x  by the second term

3x* (2x^2+2x-1)

 6x^3  +6x^2 -3x


Multiply -4  by the second term

-4*(2x^2+2x-1)

 -8x^2 -8x+4


Add these together,  lining up the terms

 6x^3  +6x^2 -3x  

            -8x^2 -8x+4

----------------------------------

6x^3  - 2x^2  -11x +4
