Answer:
(3 + 2x) + (4 – 5x) = 7 - 3x
(3 + 2i) + (4 – 5i) = 7 - 3i
Step-by-step explanation:
In the addition of two binomials you have to add separately each monomial as follows:
(3 + 2x) + (4 – 5x) =
= (3 + 4) + (2x - 5x) =
= 7 - 3x
Analogously, the sum of the complex numbers 3 + 2i and 4 – 5i is made adding the two real parts from one side, and the two imaginary parts from the other side, as follows:
(3 + 2i) + (4 – 5i) =
= (3 + 4) + (2i - 5i) =
= 7 - 3i
