rational_equations_day1_2.notebook November 21, 2016 Topic: Rational Expressions Aim: How do we solve rational equations with monomials in the denominator? HW: WS (On Website-only do #1-5 tonight) Do Now: Solve for all value(s) of x. 1) 3x+6=15 2) x2+2x=15 May 137:54 AM Joe solved the equation below and stated the solution was x=0. His teacher told him the answer cannot be zero, explain why the teacher would say that to Joe? Nov 510:44 AM 1 rational_equations_day1_2.notebook November 21, 2016 **Fractional equations will have an equal sign and result in an answer. (x=) Steps for Solving 1) Find a common denominator for each fraction. 2) Drop denominators. 4) Solve the resulting equation. 5) Check for extraneous roots. **Extraneous roots are roots that when checked do not work.
