Answer 1

here's your answer. I hope it helps ya

Answer 2

The sum of roots of the quadratic polynomials is -2.

Step-by-step explanation:

Since we have given that

$x^2+2x-3=0$

Since we know that

Sum of zeroes = $\dfrac{-b}{a}$

So, it becomes,

$\alpha +\beta =\dfrac{-b}{a}\\\\\alpha +\beta =\dfrac{2}{-1}=-2$

Hence, the sum of roots of the quadratic polynomials is -2.
