original question: [tex]\int[/tex] (x^2+2x-1)/(x(2x-1)(x+2))(adsbygoogle = window.adsbygoogle || []).push({});

the following is from my math book:

2A + B + 2C = 1

3A + 2B - C = 2

-2A = -1

okay i understand everything the math has done up to this point, this is the point that i dont get:

A = 1/2, B = 1/5, C = -1/10

i think the book got A from solving this equation: -2A = -1

I just want to know how the book got A, B, and C.
