Question

Whats the sum 3/x + 4/x^2

Answer 1

the sum is 3x+4/x^2

But that is if the x in the second part is supposed to be squared

Answer 2

`(3x+4)/(x^2)`

Explanation:

sum of
`(3)/(x) + (4)/(x^2)`

To find the sum of two fractions we need to make the denominator same

LCD is x^2. we need to get x^2 in the denominator of both fractions

Multiply the first fraction with x

`(3 \cdot x)/( \cdot x) + (4)/(x^2)`

`(3x)/(x^2) + (4)/(x^2)`

Denominators are same , now we add the numerators

`(3x+4)/(x^2)`
