Question

Find the zeros and verify the relationship between zeros and co-efficient of polynomial 4xsquare+12x+9

Answer 1

Answer:

x=-3/2; x=-3/2

Step-by-step explanation:

4x²+12x+9

4x²+6x+6x+9

2x(2x+3)+3(2x+3)

(2x+3)(2x+3)

x=-3/2; x=-3/2

∞+β=-b/a

lhs: -3/2+-3/2=-3

rhs: -12/4=-3

∞β=c/a

lhs: -3/2*-3/2=9/4

rhs: 9/4
