Given that the value of the algebraic formula (4x2 + ax-y + 6) - (2bx2-2x + 5y-1) has nothing to do with the value of the letter X, find the algebraic formula 3 (a2-2ab-b2) - (4a2 + a)

Given that the value of the algebraic formula (4x2 + ax-y + 6) - (2bx2-2x + 5y-1) has nothing to do with the value of the letter X, find the algebraic formula 3 (a2-2ab-b2) - (4a2 + a)

The value of 4x2 + ax-y + 6) - (2bx2-2x + 5y-1) has nothing to do with the value of the letter X. 4x2 + ax-y + 6) - (2bx2-2x + 5y-1) = 4x2 + ax-y + 6-2bx2 + 2x-5y + 1 = (4-2b) x ^ 2 + (a + 2) x-6y + 7, so the coefficient of X should be 04-2b = 0, a + 2 = 0 = < B = 2, a = - 23 (a2-2ab-b
