Question

plz he'll me to do this​

Answer 1

Step-by-step explanation:

4u^2 + 8u = 0

4u( u + 2) = 0

u + 2 = 0

u = -2

now, the relations between zeroes and coefficient.

sum of zeroes = -( coefficient of u)/ coefficient of u^2

= -8/4

= -2

product of zeroes = constant term / coefficient of x^2

= 0/ 4

= 0
