Question

Quick anyone know the answer to this problem?

Answer 1

Answer:

D

Step-by-step explanation:

Factor the numerators/ denominators

10 - 5 = 5(2a - 1) ← common factor of 5

4a² - 1 = (2a - 1)(2a + 1) ← difference of squares

[ Change ÷ to × and turn second fraction upside down ]

= $\frac{2a+1}{5(2a-1)}$ × $\frac{(2a-1)(2a+1)}{10a}$

[ cancel the factor (2a - 1) on the numerator/denominator ] leaving

= $\frac{(2a+1)^2}{5(10a)}$ = $\frac{(2a+1)^2}{50a}$

Answer 2

Answer Is D change dived to multiple
