## anonymous 4 years ago 3x^2-11x-20/25-x^2 simplify

1. Mertsj

$\frac{(3x+4)(x-5)}{(5-x)(5-x)}$

2. Mertsj

Note that the quotient of opposites is -1. So cancel out x-5 and 5-x and get

3. Mertsj

$\frac{-(3x+4)}{(5-x)}$

4. anonymous

so 3x+4/5-x is the answer ?

6. Mertsj

This is the answer in 2 forms:

7. Mertsj

$\frac{-(3x+4)}{(5-x)} = \frac{(3x+4)}{(x-5)}$

8. Mertsj

Revised answer:$\frac{-(3x+4)}{5+x}$
