Question

Find the zeroes of the following quadratic polynomials and verify the relationship between the zeroes and the coefficients `4u^2+8u`

Answer 1

`P(u)=4u^2+8u`
`P(u)=u(4u+8)`
P(u)=0, when u=0
4u+8=0
u=-8/4=-2
Sum of zeroes=`-(coefficient of u)/(coefficient of u^2)=-8/4=-2`
Product of zeroes=`(Constant term)/(coeffiecient of u^2)=0`
