Answer:
[tex]\frac{2x^2}{x^2-x-20}[/tex]
Step-by-step explanation:
Let's start by multiplying across. In the numerator we have:
[tex]x * 2x = 2x^2[/tex]
In the denominator, we have:
[tex](x-5)(x+4)[/tex]
We can use foil to simplify this:
[tex](x^2-x-20)[/tex]
So, we end up with:
[tex]\frac{2x^2}{x^2-x-20}[/tex]
And our answer is choice B.
