Hai friend,
here is your answer,
The polynomial is x²+7x+12
a=1,b=7,c=12
Factors of x²+7x+12
=x²+4x+3x+12
=x(x+4)+3(x+4)
=(x+4)(x+3)
Zeroes of the polynomial
x²+7x+12 =0
(x+4)(x+3)=0
x= -4,-3
ZEROES = -4, -3
SUM OF ROOTS = -4-3=-b/a=-7/1
=> -7=-7
PRODUCT OF ROOTS= -4*-3=c/a
=> 12=12
I HOPE THANKFUL FOR YOU
