Distribute the 5 across the terms in the first complex number: \(5(4 + 7i)\). This results in \(5 \times 4 + 5 \times 7i\).
Distribute the 6 across the terms in the second complex number: \(6(3 - 2i)\). This results in \(6 \times 3 - 6 \times 2i\).
Add the real parts from the results of the distributions: \(20 + 18\).
Add the imaginary parts from the results of the distributions: \(35i - 12i\).
Combine the sums of the real and imaginary parts to express the final result in standard form: \(38 + 23i\).
