Question

The roots of quadratic equation are -5 ang 3.Which of the following quadratuc equation has these roots?

Answer 1

Answer:

given roots are -5 and 3

sum of roots, S = 3 -5 = -2

and ,

product of roots, P = -5*3 = -15

so,

required quadratic equation is

x² -(S)x + p = 0

or, x² -( -2) x + (-15) = 0

or, x² +2x -15 = 0.

$.$

this is the required answer.
