Question

Need help! Please see image.

Answer 1

notice that u have
\[\large \frac{A}{D}+\frac{B}{D}-\frac{C}{D}=\frac{A+B-C}{D} \]

Answer 2

Right. But the middle term cannot be factored so it won't solve for me.

Answer 3

it doesn't matter. just do A+B-C first. then factor if possible

Answer 4

do
\[\large (2x^2+8x+20)+(3x^2-15x-44)-(4x^2-7x-15) \]
first

Answer 5

So I came up with \[x^2-14x-39\] which cannot be factored further.

Answer 6

i got
\[\large x^2-9 \]

Answer 7

which can be factored

Answer 8

Thanks got it figured out.

Answer 9

u r welcome
