Write each of the following quadratic expressions as the product of two linear factors
a) z^2 + 4i
b) z^2 + 4
c) z^2 − 4
d) z^2 − 4i

Answer with Step-by-step explanation:

Since we have given quadratic expressions in the form of

which is equal to

a) z^2 + 4i =

b) z^2 + 4 =

c) z^2 − 4 =

d) z^2 − 4i =  

Since a) and b) contains complex number so, it splits into complex linear factors.
