Answer 2

Answer:

Step-by-step explanation:

the formula of quadratic equation ia x2-(alpha+beta)+alpha*beta

alpha=2   beta=-6

so, the equation is

x2-(2+(-6))x+2*-6

x2-4x-12=0

the quadratic equation is x2-4x-12=0

proof:

x2+4x-12=0

by factorisation

x2-2x+6x-12=0

x commom

x(x-2)+6(x-2)=0

(x-2) is common

so,(x+2),(x-6) are the roots

X=2,-6
