Question

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

Answer 1

Answer:

$\frac{3x+4}{x^2}$

Step-by-step explanation:

sum of $\frac{3}{x} + \frac{4}{x^2}$

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

$\frac{3 \cdot x}{ \cdot x} + \frac{4}{x^2}$

$\frac{3x}{x^2} + \frac{4}{x^2}$

Denominators are same , now we add the numerators

$\frac{3x+4}{x^2}$

Answer 2

The sum is 3x+4/x^2

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