Question

simplified form of 9x^2-25 / 3x-5 ?

Answer 1

would the answer be
3x + 5, with the restriction x ≠ 5/ 3

Answer 2

\(\dfrac{9x^2 - 25}{3x - 5} \)

Can you factor the numerator?

Answer 3

wow my answer can't beat that

Answer 4

\(\dfrac{9x^2 - 25}{3x - 5} \)

\(= \dfrac{(3x + 5)(3x - 5) }{3x - 5} \)

\(= 3x + 5; ~~3x - 5 \ne 0 \)

\(3x - 5 = 0 \)

\(3x = 5\)

\(x = \dfrac{5}{3} \)

\(\dfrac{9x^2 - 25}{3x - 5} = 3x + 5; ~~x \ne \dfrac{5}{3} \)

You are absolutely correct.
Good job!
