We have to find $\frac{3}{5} - (\frac{1}{4})$
Let us first find least common multiplier of 5 and 4. Note that prime factorization of 5 is 5. Also, prime factorization of 4 is 2*2.
Therefore, least common multiplier of 5 and 4 is $5 \cdot 2 \cdot 2 = 20$ .
Multiply numerator and denominator of the fraction such a way that the denominator of each fraction become 20. We get $\frac{3}{5} - \frac{1}{4} = \frac{3 \times 4}{5 \times 4} - \frac{1 \times 5}{4 \times 5}$

$= \frac{12}{20} - \frac{5}{20} = \frac{12 - 5}{20} = \frac{7}{20}$

Partial Fraction Decomposition??
How do I separate this by partial fraction decomposition?

\int \frac{1}{u (u^{2} + 1)} d u

I've used the normal technique and got to:

1 = A (u^{2} + 1) + B (u)

1 = A (u^{2} + 1) + B (u)

A = 1

u = 0

BUT how do I find

B

now? because I can't make

u^{2} + 1
