Question

Evaluate the expression (3-2i)(3-2i) and write the result in the form a+bi ,where a is the real part of your answer and bis the coefficient in front of the imaginary part

Answer 1

Answer:

a = 5, b = -12

Step-by-step explanation:

By basic factoring, you get 9 - 12i + $4i^2$. Since $i^2$ is simply -1, the expression evaluates to 9 - 12i - 4, which is 5 - 12i.
