The square of a - AB = 3, the square of 4ab-3b = - 2, then the square of a + the square of 3ab-3b is

The square of a - AB = 3, the square of 4ab-3b = - 2, then the square of a + the square of 3ab-3b is

By the condition, a & # 178; - AB = 3; 4ab-3b & # 178; = - 2,
Then a & # 178; + 3ab-3b & # 178; = (A & # 178; - AB) + (4ab-3b & # 178;) = 3-2 = 1
