Simplify the expression:

(-2-2i) (-4+6i)

(-2-2i) (-4+6i)

=8-12i+8i-12i^2

=8-4i-12i^2

=4 (2-i-3i^2)

=4 ((i-1) (3i+2))

=4 (i-1) (3i+2)

Answer: (-2-2i) (-4+6i) = 20 - 4i

Step-by-step explanation:

We have the expression:

(-2 - 2i) * (-4 + 6i)

the rule we need to know here is that i*i = - 1

now, the first step is distribute the parentheses.

(-2 - 2i) * (-4 + 6i) = - 2*-4 - 2*6i - 2i*-4 - 2i*6i = 8 - 12i + 8i - 12 * (i*i)

= 8 + (8 - 12) i + 12 = 20 - 4i
