I didn't understand ​

Answer 1

Answer:

Let α=5 and β=7

α+β=5+7=12

and α×β=5×7=35

The required quadratic equation is

x

2

−(α+β)x+α.β=0

∴ x

2

−12x+35=0

Answer 2

4)

• Roots are 5 and -7.

•°• α = 5

β = -7

• Required Condition for Quadratic equation is:

=> x² - (α+β) + αβ = 0

x² - ( 5 - 7)x + (-35) = 0

x² + 2x - 35 = 0. is equation
