Basic instructions for the worksheets Each worksheet is randomly generated and thus unique. For example:. To rationalize the denominator, multiply by the complex conjugate of the denominator. With this worksheet generator, you can make printable worksheets for simplifying variable expressions for pre-algebra and algebra 1 courses. You combine the imaginary parts the terms with iand you combine the real parts. The great thing is you have no new rules to worry about—whether you treat it as a variable or a radical, the exact same rules apply to adding and subtracting complex numbers. The quotient can be written in the form. Replace i 2 with —1. When you multiply expressions with the same exponent but different bases, you multiply the bases and use the same exponent.

The terms of an expression are the parts of a mathematical expression that are separated by a plus (+) or minus (-) sign.
