The cubic power of a minus the square of a times the square of B = 2, the square of a times the square of B - the cubic power of B = 5, find the cubic power of a - the cubic power of B

The cubic power of a minus the square of a times the square of B = 2, the square of a times the square of B - the cubic power of B = 5, find the cubic power of a - the cubic power of B

Because a & sup2; × B & sup2; - B & sup3; = 5
So a & sup2; × B & sup2; = 5 + B & sup3;
Because a & sup3; - A & sup2; × B & sup2; = 2
So a & sup3; - (5 + B & sup3;) = 2
So a & sup3; - B & sup3; = 2 + 5 = 7
