It is known that a real number root of the quadratic equation AX2 + BX + C = 0 with one variable about X is x = - 2. Find the value of the algebraic formula 4a-2b + c-2013

It is known that a real number root of the quadratic equation AX2 + BX + C = 0 with one variable about X is x = - 2. Find the value of the algebraic formula 4a-2b + c-2013

A real root of the quadratic equation AX2 + BX + C = 0 with one variable of X is x = - 2
4a-2b+c=0
∴4a-2b+c-2013=-2013
