hi

can anyone check if my answers are correct?

Integrate:-

1. [(2)x^3 - (3)x^2 + 3x - 4]/ (x^2) - 2x +1 =

1/2 x^2 + x + 3 ln (x-1) + 2/(x-1)

2.(7x+2)/(3x+1)(2x-3)^2 =

4/121 ln(2x-3) - 9/21 ln (3x+1) + 25/11 (2x-3)^3 / 6

3. (2)x^3 + (5)x^2 - 3/ (x^2 - 1)(x^2 + 3) =

1/6 ln (x^2 + 3) - 1/2 ln (x^2 +1)

4. 4(x^2 - 5)/(2x+1)(x+3) =

2x - 19/5 ln (2x+1) - 16/5 ln (x+3)
