Question

The area of a rectangular picture frame is given by the trinomial 3x^2 - 9x - 30

Answer 1

use factoring

Answer 2

First factor 3
3(x^2-3x-10)

Answer 3

ok

Answer 4

3(x-5)(x+2)

Answer 5

then what?

Answer 6

It all

Answer 7

Now let me check my answer choices
and thank you. :)

Answer 8

Finding the GCF is only the first step in this problem.
\(3x^2 - 9x - 30\)
We know that the GCF is 3
\(3(x^2 - 3x - 10)\)

But then the trinomial that is inside of the parenthesis needs to be factored as well because it is still a quadratic within standard form (\(ax^2 + bx + c\)).
