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 ]

= [tex]\frac{2a+1}{5(2a-1)}[/tex] × [tex]\frac{(2a-1)(2a+1)}{10a}[/tex]

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

= [tex]\frac{(2a+1)^2}{5(10a)}[/tex] = [tex]\frac{(2a+1)^2}{50a}[/tex]
