Question

please solve this quescise​

Answer 1

x=-4 or 2

let the solution are 'a' and 'b'

therefore,

a+b= -2

-4+2=-2

and,

ab= -8

-4×2= -8

Answer 2

xsquare-2x-8

xsquare-4x+2x-8=0

x (x-4)+2(x-4)

x-4=0 or x+2=0

x=4 or x=-2;alpha=4 beta=-2

sum of zeros=a+b

=4+(-2)

=4-2

=2

product of zeroes=a×b

=4×-2

=-8

let a=1 b=-2 c=-8

sum of zeroes=-b/a

=-(-2)/1

=2

product of zeroes=c/a

=-8/1

=-8
