Identify Parts: Identify the real and imaginary parts of each complex number.The real part of the first complex number 1.5−2.9i is 1.5, and the imaginary part is −2.9i.The real part of the second complex number 4.3+1.4i is 4.3, and the imaginary part is 1.4i.
Add Real Parts: Add the real parts of the complex numbers.Add 1.5 (the real part of the first complex number) to 4.3 (the real part of the second complex number).1.5+4.3=5.8
Add Imaginary Parts: Add the imaginary parts of the complex numbers.Add −2.9i (the imaginary part of the first complex number) to 1.4i (the imaginary part of the second complex number).−2.9i+1.4i=−1.5i
Combine Results: Combine the results from Step 2 and Step 3 to find the sum of the complex numbers.The sum of the real parts is 5.8, and the sum of the imaginary parts is −1.5i.Therefore, the sum of the complex numbers is 5.8−1.5i.
