Rational Equation Problem Solving

When finding the LCD of a problem involving the addition or subtraction of fractions it may be necessary to factor some denominators to discover some restricted values that is values that if used make the denominator of one or more of the fractional terms zero. Students develop their problem-solving and modeling abilities by carefully reading the problem description and converting information into equations MP1 thus creating a mathematical model of the problem MP4.
