Step-by-step explanation:
<em><u>multiplying/dividing rational expressions</u></em>
The course of action of multiplying and dividing the Rational expressions is same as multiplying and dividing the numeric fractions.
To multiply
- First determine the greatest common factors of the numerator and denominator.
- Then, regrouping the factors to make fractions equal to one.
- Then, multiplying any remaining factors.
For example,
Find if there are excluded values - values of a which can generate 0 as a denominator
The domain is all a ≠ 0
As
So,
To Divide
- First rewriting the division as multiplication by the reciprocal of the denominator
- The remaining steps are then the same as for multiplication.
For example,
x can not be zero i.e. x ≠ 0
Therefore, the main difference between multiplying/dividing rational expressions is during multiplying we
- First determine the greatest common factors of the numerator and denominator
and during dividing we
- First rewrite the division as multiplication by the reciprocal of the denominator
<u><em>Adding/subtracting rational expressions</em></u>
If the two rational expressions that we would like to want to add or subtract have the same denominator we just add/subtract the numerators which each other.
For example, when we add two rational expressions
And when we subtract two rational expressions
