Question

find the zeroes of the following quadratic polynomials and verify the relationship b/w the zeroes and the coefficients: 4u2+8u

Answer 1

find the Q.P.[Quadratic polynomials]

1. 4u2+8u

first we take comman

'4' and 'u' r common.

4u[u+2]

so,

4u=0 and u+2=0

u=0/4 and u= -2

u=0 and u= -2

this r the zeroes.

now relationship,

sum of the zeroes= -b/a=-8/4= -2

and

product of the zeroes=c/a = [c is not there so we let c=o]

c/a=0/4 =0

Ans.

ok tnx.
