The calculator tool used for adding the given rational expressions is called as the Adding Rational expression calculator. A Rational expression is the expression which has polynomials on numerator or denominator or both. To add the rational expressions, the key point is to make the denominator the same expression.

Find the answer for the expression 2 x³/5 + 5 x³/6?

The given question is on Adding rational expressions.

This question contains adding with the same polynomial x³.

The first step of the question is to calculate the LCM of the denominators which are 5 and 6, is 30.

Now 2/5 and 5/6 can be added with the LCM of the denominators as 30.

This makes the solution 2 x³/5 + 5 x³/6 = 12x3/30 + 25x3/30 = 37x3/30.

Example 2: Find the answer for the expression 3 x/ 4 + 2 x/ 7?

The given question is on Adding rational expressions.

The first step of the question is to calculate the LCM of 4 and 7 which is 28.

Now 3/4 and 2/7 can be added with the LCM of the denominators as 28.

3 x/ 4 + 2 x/ 7= [(3*7) x / (4*7)] + [(2*4) x / (7*4)] = 21x/28 + 8x/28

This makes the solution = 29 x/28.
