Answer:  [tex]-6(2x+1)(x-1)[/tex]

Step-by-step explanation:

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

[tex]-12x^2+6x+6[/tex]

She can also factor out -6:

[tex]-6(2x^2-x-1)[/tex]

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

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

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

Now she needs to group the terms as following:

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

And factor out 2x:

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

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

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

Answer:

-12x^2+6x+6
