Answer:  -6(2x+1)(x-1)

Step-by-step explanation:

Given the expression in the form 5x-4x^2-1+x-8x^2+7, we know that Victoria can simplify it by adding the like terms:

-12x^2+6x+6

She can also factor out -6:

-6(2x^2-x-1)

Now, she needs  to factor the coefficient of the second term rewrite it as (1-2), then:

-6(2x^2+(1-2)x-1)

-6(2x^2-2x+x-1)

Now she needs to group the terms as following:

-6[(2x^2-2x)+(x-1)]

And factor out 2x:

-6[2x(x-1)+(x-1)]

Finally, she has to factor out (x-1). Therefore, she gets:

-6(2x+1)(x-1)
