Rational expression in simplest form. 2 2 x 8x 16 2x 8 c 6c 9 3c 9 y 6. Click the blue arrow to submit and see the result. Y-value of a rational expression in simplest form is zero when and only when the expressions numerator is equal to zero.

The quotient of two polynomial expressions is called a rational expression. The general formulas are as follows a b c d ac bd a b c d a c b d a b c d a b c d a b d c a b c d a b c d a b d c Note the two different forms for denoting division. Lets start with multiplying and dividing rational expressions.

To do this we first need to factor both the numerator and denominator. In General A rational function is the ratio of two polynomials P x and Q x like this f x P x Q x Except that Q x cannot be zero and anywhere that Q x0 is undefined Finding Roots of Rational Expressions A root or zero is where the expression is equal to zero. 2 D5 5 4.

Note that it is clear that x 0 3 Cancel the common factor 4 If possible look for other factors that are common to the numerator and denominator. The calculator works for both numbers and expressions containing variables. Then simplify the sum.

A rational expression just refers to a fraction with a polynomial in the numerator and a polynomial in the denominator. Here are a few examples. The numerator and denominator must be in expanded form ie not a product of factors.

121721 321 PM Rational Expressions Book exercises 36 Divide and simplify. Assume that all variables result in nonzero denominators. We can apply the properties of fractions to rational expressions such as simplifying the expressions by canceling common factors from the numerator and the denominator.

Subtract out the common factors. That means that as long as there are no common factors between the numerator and the denominator you need not worry about the denominator when you are looking for zeros. 7x 7y 21 y x 4x 4y y.

In other words a rational expression is defined as an algebraic expression which can be written as a ratio of two polynomial expressions. Able to display the work process and the detailed explanation. Adding rational expressions with the same denominator is the simplest place to start so lets begin there.
