Calc Simplifying Complex Expressions by Factoring Page 1 of 1 Simplifying Complex Expressions and Solving Equations by Factoring Summary: Solve complex equations by factoring. To review factoring, see Precalculus Review and Algebra 2 Review topics. Example: Simplify solution: There is a common factor of xe2x. Factor to get Example: Solve the equation . solution: First simplify by factoring out the common factor: . Now use the zero-product property, “a product can be zero only if one of its factors is zero.” Therefore, either , which is impossible, or , which makes x = -2 or x = 2.
