Answer:
[tex]\frac{w^{2} - 7w + 12}{w^{2}+w-20 }[/tex]
Step-by-step explanation:
[tex]\frac{w - 3}{w + 5}[/tex] x [tex]\frac{(w-4)}{(w-4)}[/tex] Multiply the top and bottom by (w - 4) to get w² + w - 20 as a denominator.
(w - 3)(w - 4) Factor the equation
w² - 7w + 12
Now put together the fraction
[tex]\frac{w^{2} - 7w + 12}{w^{2}+w-20 }[/tex] is equivalent to [tex]\frac{w - 3}{w + 5}[/tex]
