Adding and Subtracting Rational Expressions
Adding and Subtracting Rational Expressions
Standard
A.APR.7... add, subtract, multiply, and divide rational expressions. Also N.Q.2, A.SSE.2
You can use the same rules to add and subtract rational expressions that you use to add and subtract numerical fractions. You can add the numerators of rational expressions with lie denominators. If a, b, and c represent polynomials (with c can not equal to 0), then a/c + b/c = (a+b)/c.
