Question

from quadratic equation if root are -3and-8​

Answer 1

Answer:

Step-by-step explanation: The roots are (-3) and (-8).

Let alpha = -3 and beta = -8.

The quadratic equation whose roots are alpha and beta is given by,

f(x) = x^2 - (alpha+beta)x + (alpha*beta)

= x^2 - (-3-8)x + (-3)*(-8)

= x^2 - (-11)x + 24

= x^2 + 11x + 24

Answer 2

If the given roots are -3 & 8

Consider,

α=-3

β=-8

General form of a qudratic equation is

x^2 + (α+β)x +αβ

Therefore equation is

x^2 -11x + 24
