Simplifying Complex Expressions
This article will guide you through the process of simplifying the complex expression: (1 - i) - (7 - 3i) - (2 + i) + (6 - 2i).
Understanding Complex Numbers
Complex numbers are numbers that can be expressed in the form a + bi, where 'a' and 'b' are real numbers, and 'i' is the imaginary unit, defined as the square root of -1.
Simplifying the Expression
-
Distribute the negative signs:
- (1 - i) - (7 - 3i) - (2 + i) + (6 - 2i) = 1 - i - 7 + 3i - 2 - i + 6 - 2i
-
Combine real and imaginary terms:
- (1 - 7 - 2 + 6) + (-1 + 3 - 1 - 2)i
-
Simplify:
- -2 - i
Conclusion
The simplified form of the complex expression (1 - i) - (7 - 3i) - (2 + i) + (6 - 2i) is -2 - i.
Remember that when simplifying complex expressions, the key is to treat 'i' as a variable and follow the rules of algebra.
