Add, subtract, multiply and divide rational expressions
Rational expressions are fractions that consist of polynomials in the numerator and denominator. Operations such as addition, subtraction, multiplication, and division can be performed on rational expressions similar to those on numeric fractions.
Adding or subtracting rational expressions involves finding a common denominator, combining like terms, and then simplifying the resulting expression.
Multiplying rational expressions requires multiplying the numerators together and the denominators together, then simplifying by factoring and canceling out common factors.
Dividing rational expressions is done by multiplying the first expression by the reciprocal of the second expression, then simplifying the resulting expression.
It is important to simplify the rational expressions by factoring out common factors before performing the operations to get the most simplified form.
