Multiplying Rational Numbers Operation On Rational Numbers Youtubeо Check your answers on your own answers1) 2 2 52) 1 83) 9.184) 3.785) 7 7 86) 72this video is about how to multiply and divide both positive and negative. So when we multiply, you just multiply the numerator and multiply the denominator, so you have 3x squared y times 14a squared b in the numerator. then in the denominator, we have 2ab times 18xy squared. let's see where we can simplify this thing. we can divide the 14 by 2, and the 2 by 2, and we get 14 divided by 2 is 7, and 2 divided by 2 is 1. The short solution is as follows: example 2. find the value of the expression. this is a multiplication of rational numbers with different signs. multiply the modules of these numbers and put minus in front of the answer: the solution for this example can be written in a shorter form: example 3. All right, now let's work through this together. so multiplying rational expressions like this, it's very analogous to multiplying fractions. for example, if i were to multiply 6 25 times 15 9, there's a few ways you could do it. you could just multiply six times 15 in the numerator, and 25 times nine in the denominator.

Example 1: 3 x 2 2 ⋅ 2 9 x. we can multiply rational expressions in much the same way as we multiply numerical fractions. = 3 x 2 2 ⋅ 2 9 x = 3 ⋅ x ⋅ x 2 ⋅ 2 3 ⋅ 3 ⋅ x factor numerators and denominators ( note x ≠ 0) = 3 ⋅ x ⋅ x 2 ⋅ 2 3 ⋅ 3 ⋅ x cancel common factors = x 3 multiply across. recall that the original. Definition 5.1.1. a rational expression is an expression of the form p q, where p and q are polynomials and q ≠ 0. here are some examples of rational expressions: − 24 56 5x 12y 4x 1 x2 − 9 4x2 3x − 1 2x − 8. notice that the first rational expression listed above, − 24 56, is just a fraction. since a constant is a polynomial.
