Question

integral (3x^2 +x+4)/(x^3+x)

Answer 1

\[\int\limits (3x^2 +x+4)/(x^3+x)\]

Answer 2

(3x^@+x+4)/[x(x^2+1)]=a/x+bx/(x^2+1)

Answer 3

find a,b

Answer 4

well, I dont know when to use Bx. can you please explain it?

Answer 5

i used Bx + C and got a result that checks out

i got 4 / x^2 + 1 /(x^2 + 1) - x /( x^2 + 1)

Answer 6

when ur denominator is a quadratic then use bx+c
