Victoria was given the expression 5x - 4x^2-1+x-8x^2+7 and asked to
simplify it. how can she simplify the expression?

Step-by-step explanation:

Given the expression in the form , we know that Victoria can simplify it by adding the like terms:

She can also factor out -6:

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

Now she needs to group the terms as following:

And factor out 2x:

Finally, she has to factor out . Therefore, she gets:
