Question

PLEASE HELP ME, I DON'T UNDERSTAND! :(

Answer 1

(x + 1) (x + 2) / 2

Explanation:

(x² − 4x − 5) / (x − 2) ÷ (2x − 10) / (x² − 4)

To divide by a fraction, multiply by its reciprocal.

(x² − 4x − 5) / (x − 2) × (x² − 4) / (2x − 10)

Factor.

(x − 5) (x + 1) / (x − 2) × (x − 2) (x + 2) / (2 (x − 5))

Reduce.

(x + 1) × (x + 2) / 2

(x + 1) (x + 2) / 2
