if ax²+bx+c is a quadratic equation. IF two persons A and B are there.if A person wrote the constant term c, wrong, he got roots as 8,2. IF B person wrote the coefficient of x² wrong he got roots as -9,-1.then find the actual quadratic equation and their roots?

Hey

The quadratic eqn for person A,

------------------(1)
Comparing this with the standard form

we get,
b/a = -10

Now the quadratic Eqn for person B is :-



In this the leadingcoefficient is wrong
Comparing this with the standard form
we get, c/a = 9


so b = -10a and c= 9a

so QE will be
