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

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

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

Multiply (2 + -3i) * (3 + 5i)
(2(3 + 5i) + -3i * (3 + 5i)) = 0
((3 * 2 + 5i * 2) + -3i * (3 + 5i)) = 0
((6 + 10i) + -3i * (3 + 5i)) = 0
(6 + 10i + (3 * -3i + 5i * -3i)) = 0
(6 + 10i + (-9i + -15i2)) = 0

Combine like terms: 10i + -9i = 1i
(6 + 1i + -15i2) = 0
