If the square of 3x (2a + B + 1) + the square of 5Y (a-2b-1) = 10 is a quadratic equation with respect to X and y, find a-b

If the square of 3x (2a + B + 1) + the square of 5Y (a-2b-1) = 10 is a quadratic equation with respect to X and y, find a-b

They are binary linear equations, linear, so 2A + B + 1 = 1, a-2b-1 = 1
