Question

10n^2-250/3n+15 how do you simplify this rational expression ?

Answer 1

Explanation:

(10n² − 250) / (3n + 15)

Factor 10 from the numerator, and 3 from the denominator.

10 (n² − 25) / (3 (n + 5))

Factor the difference of squares:

10 (n − 5) (n + 5) / (3 (n + 5))

Divide n + 5 from the top and bottom:

10 (n − 5) / 3
