Math Problem Statement

(3i-7)+(8i-2)

Solution

To simplify the expression (3i7)+(8i2)(3i - 7) + (8i - 2), we combine like terms.

  1. Combine the imaginary parts: 3i+8i=11i3i + 8i = 11i

  2. Combine the real parts: 72=9-7 - 2 = -9

Putting it all together: (3i7)+(8i2)=11i9(3i - 7) + (8i - 2) = 11i - 9

So, the simplified expression is: 11i911i - 9

  5. How do we multiply two complex numbers, such as (3i7)(3i - 7) and (8i2)(8i - 2)?

Tip: When dealing with complex numbers, remember that real and imaginary parts are combined separately, just like adding terms in a polynomial.
