(3-2i)(5+2i)=

Solution for (3-2i)(5+2i)= equation:

Simplifying
(3 + -2i)(5 + 2i) = 0

Multiply (3 + -2i) * (5 + 2i)
(3(5 + 2i) + -2i * (5 + 2i)) = 0
((5 * 3 + 2i * 3) + -2i * (5 + 2i)) = 0
((15 + 6i) + -2i * (5 + 2i)) = 0
(15 + 6i + (5 * -2i + 2i * -2i)) = 0
(15 + 6i + (-10i + -4i2)) = 0

Combine like terms: 6i + -10i = -4i
(15 + -4i + -4i2) = 0

Solving
15 + -4i + -4i2 = 0

Solving for variable 'i'.
