Step-by-step explanation:

root α=5 and β=−2

Then sum of roots =α+β=5−2

⇒α+β=3

And product of roots =αβ=5×(−2)

⇒αβ=−10

hence , required equation whose roots are 5 and −2

x

− ( sum of roots) x + product of roots =0

⇒x

−3x+(−10)=0

⇒x

−3x−10=0

Hence required equation is x

−3x−10=0 whose roots are 5 and −2
