invert, factor, cancel and then multiply at the end. start with $\frac{(x^2+9x+20)(x-4)}{(x^2-25)(x+4)}$

3. anonymous

factor next, both numerator and denominator. then cancel the common factors top and bottom

4. anonymous

how do you do it

5. anonymous

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