Answer 2

hello mate!!


let the quadratic equation be ax^2+bx+c

so, sum of zeroes=-b/a
=8

product of zeroes=c/a
=12

let a=1, then b=-8 and c=12

so, quadratic equation is x^2-8x+12

now, x^2-8x+12=0
x^2-6x-2x+12=0
x(x-6)-2(x-6)=0
(x-2)(x-6)=0
x-2=0. x-6=0
x=2. x=6


so, the zeroes are 2 and 6

hope it helps!!
