Suppose a,b denotes the distinct real roots of the quadratic polynomia

1.	Suppose a,b denotes the distinct real roots of the quadratic polynomial x2+20x−2020 and suppose c,d denotes the distinct complex roots of the quadratic polynomial x2−20x+2020.Then the value of ac(a−c)+ad(a−d)+bc(b−c)+bd(b−d) is
Answer» Suppose $a, b$ denotes the distinct real roots of the quadratic polynomial $x^{2} + 20 x - 2020$ and suppose $c, d$ denotes the distinct complex roots of the quadratic polynomial $x^{2} - 20 x + 2020.$ Then the value of $a c (a - c) + a d (a - d) + b c (b - c) + b d (b - d)$ is
