Question

find the the sum and product of the following quadratic polynomial 5 x square +3x-2

​

Answer 1

Answer:

5x²+3x-2=0.

Comparing the above equation with

ax²+bx+c=0 we get,

a=5 , b=3 , c=-2

Now,

Let alpha and beta be the roots of give quadratic equation,

sum of the roots:

. alpha + beta = -b/a

=-3/5

and, Product of the roots:

alpha×beta=c/a

=-2/5
