Question

What is the sum? 2/x^2+4/x^2

Answer 1

\frac{2}{ x^{2} } + \frac{4}{ x^{2} } = \frac{2+4}{ x^{2}}= \frac{6}{ x^{2} }

Explanation:

When we add two expression in fraction we take Least common multiple of two expression in the denominator

Here we have expression

Now, we write a common denominator

rewrite the expression

Now, we combine the numerator 2+4 is equal to 6

So, we will get = \frac{2}{x^{2}}+ \frac{4}{x^{2}} =\frac{6}{x^{2} }

Hope this helps!
