Question

Simplify completely quantity x squared minus 100 over quantity x squared plus 2 x minus 120 divided quantity 6 x plus 60 over quantity x minus 2

Answer 1

Didn't we already do this?

\(\dfrac{x^{2} - 100}{x^{2} + 2x - 120} / \dfrac{6x+60}{x-2}\)

Reciprocal and Multiply.

\(\dfrac{x^{2} - 100}{x^{2} + 2x - 120}\cdot\dfrac{x-2}{6x+60}\)

Factor until everything is factored.
