Question

find the zeroes of the following quadratic polynomials and verify the relationship between the zeroes and the coefficients: 4u²+8u in the chapter of polynomials for 10th class.

Answer 1

4u^2+8u=0
4u(u+2)=0
4u=0
u=0
and
u+2=0
u=-2
u=0 or -2

Answer 2

4u²+8u=0
4u(u+2)=0
4u=0
u+2=0
u=-2
u=0
