ADDING AND SUBTRACTING RATIONAL EXPRESSIONS WITH LIKE DENOMINATOR
Addition of Rational expression :
To add rational expressions with a like denominators, we will put only one denominator and add the numerators. If it is possible, reduce it into lowest terms and get the result.
If p, q, and r are polynomials where r ≠ 0, then
Subtraction of Rational expression :
To subtract rational expressions we will put only one denominator and subtract the numerators. If it is possible, reduce it into lowest terms and get the result.
If p, q, and r are polynomials where r ≠ 0, then
Problem 1 :
Solution :
Since the denominators are the same, add the numerators.
Problem 2 :
Solution :
Since the denominators are the same, add the numerators.
Problem 3 :
