If a and b are different values and a – b = 2(√a - √b), then in terms of b, a equals: Choose the correct choice from the following answers
A) √b
B) b
C) b - 4√b + 4
D) b + 2√b + 1
E) b^2 – 2b√b + b
(√a)^2 - (√b)^2 = 2(√a - √b) -----&gt; ( √a + √b) ( √a - √b) = 2(√a - √b ) -------&gt; √a + √b = 2, so   √a = 2 - √b, square both sides and solve. Answer is b - 4√b + 4.
