To simplify the evaluation, we know | 2a-b + 1 | + (3a + 3 / 2 b) & sup2; = 0, find the algebraic formula B & sup2 / / A + B △ A / a-b - 1) x (a - A & sup2 / / a) Note: B & sup2 / A + B is the square of a + B Find the value of the Algebra B & sup2; / (a + b) / {A / (a-b) - 1} x {a - A & sup2; / (a + b)}

The so-called dialogue 1: ∵ | 2a-b + 1 | + (3a + 3 / 2b) & sup2; = 0 and | 2a-b + 1 | ≥ 0, (3a + 3 / 2b) & sup2; ≥ 0 ∵ 2a-b + 1 = 0, 3A + 3 / 2B = 0, the solution is a = - 1 / 4, B = 1 / 2 ∵ [B & sup2; / (a + b)] / [A / (a-b) - 1] × [A-A & sup2; / (a + b)] = [B & sup2; / (a + b)] / [
