Question

Can anyone help me with this algebra 2 problem?

(the topic is simplifying and multiplying rational expressions)

Answer 1

4. 2(x+5)

Explanation:

`\displaystyle(\left((x^2-25)/(14)\right))/(\left((x-5)/(28)\right))=((x+5)(x-5))/(14)\cdot(28)/((x-5))\\\\=2(x+5)`

Of course, 28 = 2·14 and like factors in the numerator and denominator cancel.
