Question

5) Roots of a quadratic equation are 5 and -4 then form the quadratic
equation​

Answer 1

Step-by-step explanation:

(x-5)(x+4)

x^2+4x-5x-20

x^2-x-20

Answer 2

let (a+B)=5 and (a•B) = -4

therefore,

By using formula

x2- (a+B)x + a•B= 0

x2- 5x-4= 0

Hence, we get quadratic equation x2-5x-4=0
