Answer: ![-6(2x+1)(x-1)](https://tex.z-dn.net/?f=-6%282x%2B1%29%28x-1%29)
Step-by-step explanation:
Given the expression in the form
, we know that Victoria can simplify it by adding the like terms:
![-12x^2+6x+6](https://tex.z-dn.net/?f=-12x%5E2%2B6x%2B6)
She can also factor out -6:
![-6(2x^2-x-1)](https://tex.z-dn.net/?f=-6%282x%5E2-x-1%29)
Now, she needs to factor the coefficient of the second term rewrite it as (1-2), then:
![-6(2x^2+(1-2)x-1)](https://tex.z-dn.net/?f=-6%282x%5E2%2B%281-2%29x-1%29)
Now she needs to group the terms as following:
And factor out 2x:
Finally, she has to factor out
. Therefore, she gets:
