answer 4

Step-by-step explanation:

2(x  2  −1)+3x(x−4)

Use the distributive property to multiply 2 by x ^2   −1.

2x^2 −2+3x(x−4)

Use the distributive property to multiply 3x by x−4. 2

2x^2  −2+3x  2  −12x

Combine 2x^ 2   and 3x ^2   to get 5x ^2  .

5x  2  −2−12x

Then put it in its formula order and you get

5x^2 -12x -2

kinda hard to do with it in this but i hope this helps
