Question

Integrate 1/((x-1)(x+2))

Answer 1

it looks ready to turn into partial fractions

Answer 2

\[\frac{1}{(x-1)(x+2)}=\frac{A}{x-1}+\frac{B}{x+2}\]
when x=1; A = 1/3

when x = -2; B = -1/3 if i see it right

Answer 3

\[\int\frac{1}{3(x-1)}-\frac{1}{3(x+2)}dx\]

Answer 4

yes you do the "french method" and you see it right away.
