If a and b are different values and a – b = 5(√a - √b), then in terms of b, a equals:  Choose the correct choice from the following answers:
A) √b  B) b  C) b - 2√b + 1  D) b - 10√b + 25  E) b^2 – 2b√b + b
(√a)^2 - (√b)^2 = 5(√a - √b) -----&gt; ( √a + √b) ( √a - √b) = 5(√a - √b) -------&gt; √a + √b = 5, so   √a = 5 - √b, square both sides and solve. Answer is b - 10√b + 25.
