(3-8i)(1-5i)=

Solution for (3-8i)(1-5i)= equation:

Simplifying
(3 + -8i)(1 + -5i) = 0

Multiply (3 + -8i) * (1 + -5i)
(3(1 + -5i) + -8i * (1 + -5i)) = 0
((1 * 3 + -5i * 3) + -8i * (1 + -5i)) = 0
((3 + -15i) + -8i * (1 + -5i)) = 0
(3 + -15i + (1 * -8i + -5i * -8i)) = 0
(3 + -15i + (-8i + 40i2)) = 0

Combine like terms: -15i + -8i = -23i
(3 + -23i + 40i2) = 0

Solving
3 + -23i + 40i2 = 0
