Question

if roots are -3 and -7 then form quadratic equation​

Answer 1

Answer:

Step-by-step explanation:

Alpha + beta = -3+(-7) =-10

Alpha. Beta = -3×-7 = 21

Eq = x² - (alpha + beta)x + (alpha. Beta)

= x²-(-10)x+21

= x²+10x+21

Answer 2

Answer:

let we take α⇒-3

                   β⇒-7

quadratic form  x^2-(α+β)x+α*β=0

by putting value of α&β

then,

x^2-(-3-7)x+(-3*-7)=0

x^2 + 10x+21=0
