Question

how to find other root ?if you have have got answer in quadratic equation?

Answer 1

You can simply find the other root by using the relationship of zeroes/roots of quadratic equation to it's coefficients

For instance, lets take a quadratic equation ax² + bx + c = 0

And it's roots to be x_1 & x_2

Therefore,

x_1+x_2 = (-b/a)

&

x_1×x_2 = (c/a)

Put value of that root in any of the above relationship and you will find your desired answer!

Hope it helps you!
