you have to simplify the top and cancel out any denominators that equal to nominators

denominator must be equal that you can perform easy operation in them

Multiplying Rational Expressions After studying this lesson, you will be able to: * Multiply rational expressions. Steps to multiply a rational expression: 1. Cancel numerator to denominator if possible (don't cancel parts of a binomial or trinomial) 2. Factor the numerators and denominators if possible. 3. Multiply straight across - remember, you don't need a common denominator to multiply fractions (or rational expressions). Example 1 Nothing will cancel. Nothing will factor. All we have to do is multiply. This is the simplified answer. Example 2 We can do some canceling and reducing in this problem. 2 and 16 reduces; 9 and 3 reduces, reduce the variables. Now, we multiply. This is the simplified expression. Example 3 We can reduce 12 and 3 and reduce the variables Now, factor the second denominator. Cancel the identical binomials (x + 5 ) This is the simplified expression. Example 4 Factor Cancel the identical binomials. This is the simplified expression. Example 5Factor Cancel the identical binomials. This is the simplified expression. THIS WAS MADE BY: www.algebra-online.com/multiplying-rational-expressions-1.htm Hope this helped !

In some simple cases, factoring allows you to find solutions to a quadratic equations easily.Factoring works best when the solutions are integers or simple rational numbers. Factoring is useless if the solutions are irrational or complex numbers. With rational numbers which are relatively complicated (large numerators and denominators) factoring may not offer much of an advantage.

In order to subtract two rational expressions by simply subtracting their numerators you must make sure that their denominators are equal.

Suppose X1 = N1/D1 and X2 = N2/D2 are two rational expressions, where the numerators N1 and N2 and denominators D1 and D2 are simpler expressions. Then X1 * X2 = (N1*N2)/(D1*D2) and X1 / X2 = (N1*D2)/(D1*N2).

Yes. Fractions whose numerators and denominators are integers are rational numbers. Being negative does not change it into an irrational number.

multiplying rational expressions means multiplying two alg. rxpressions that look like fractions, Just like normal, multiply numerators and multiply denominators then reduce. Division, just like regular fractions means to invert the divisor and the multiply (as above)

You add the numerators and put over the denominator.

You subtract the numerators, and place it over the common denominator.

Do you have a specific example? Try to simplify and eliminate the denominators.

When multiplying two rational expressions, simply multiply their numerators together, and their denominators together: (a / b) * (c / d) = (a * c) / (b * d) Dividing one fraction by another is the same as multiplying the first fraction by the reciprocal of the second one: (a / b) / (c / d) = (a / b) * (d / c) = (a * d) / (b * c) This is often referred to as cross multiplication.

Yes, eg 13/17 - 4/17 = 9/17

Find a common denominator, which can always be accomplished by multiplying the two denominators together. Then convert each original fraction to the new denominator by multiplying both numerator and denominator by a number that will make the denominator of each fraction the same, then add the converted numerators and express the sum as a new fraction with the sum of the converted numerators divided by the common denominator. For example, a/b + c/d = (da + bc)/bd.
