Question 1. Find the zeroes of the following quadratic polynomials and verify the relationship between the zeroes and the coefficients.
(iii) 4u² + 8u

1. Find the zeroes of the following quadratic polynomials and verify the relationship between the zeroes and the coefficients.
(iii) 4u² + 8u

 (iv) 4u² + 8u
Factorize the equation

Compare the equation with au²  + bu + c    = 0
We get
a = 4 ,b=-8 c= 0
To factorize the value  we can take 4u common there
4u(u+2)            = 0
First zero

4u                    = 0
U                      = 0  
second zero
u+2                  = 0
u                      = - 2  

sum of zero                             0 - 2             = - 2
product of zero                       0 x ( - 2 )        = 0

Sum  of zero                          -b/a               = -(8/4)            = -2
Product of zero                        c/a               =  0/4              =  0
