1.Suppose a,ba,ba,b denote the distinct real roots of x2+20x−2020x^2+20x-2020x2+20x−2020 and c,dc,dc,d denote the distinct complex roots of x2−20x+2020x^2-20x+2020x2−20x+2020. Then the value of ac(a−c)+ad(a−d)+bc(b−c)+bd(b−d)ac(a-c)+ad(a-d)+bc(b-c)+bd(b-d)ac(a−c)+ad(a−d)+bc(b−c)+bd(b−d) isa.000b.800080008000c.808080808080d.160001600016000Login to continueOnly logged in users canattempt or see the solution.
