Question

1. Obtain a quadratic equation whose sum and
product of the roots are respectively 3 and -5. ​

Answer 1

Step-by-step explanation:

x = 3 & x = -5

(x-3)*(x+5) = 0

(x^2 + 5x -3x - 15) = 0

x^2 + 2x -15 = 0

is the required quadratic equation

Answer 2

we have to apply the formula as given in ans.
