Answer: 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
