Answer:
Step-by-step explanation:
Given ,
5z² + 3z
We need to factorize above expression:
So , Let f(z) = 5z² + 3z
Taking out z, we get
or f(z) = z(5z + 3) , This is the factorize form
if we plug f(z) =0
i.e z(5z + 3) = 0
z = 0 , 5z+ 3 = 0
or z = 0, z = -3/5
Hence z =0 and z= -3/5 are the roots of f(z).
