Question

simplify to lowest terms..9a^2/3a+5b-25b^2/3a+5b

Answer 1

both fractions have the same denominator

so they can be written as

\[\frac{9a^2 - 25b^2}{3a + 5b}\]


the numerator is the difference of 2 squares... you will need to factor the numerator and then there will be an obvious common factor to cancel.
