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).
