Integral of (4x-3)/(2x^2-3x-7) dx
The solution
You have entered
[src]
1 / | | 4*x - 3 | -------------- dx | 2 | 2*x - 3*x - 7 | / 0
$$\int\limits_{0}^{1} \frac{4 x - 3}{2 x^{2} - 3 x - 7}\, dx$$
Detail solution
We have the integral:
/ | | 4*x - 3 | 1*-------------- dx | 2 | 2*x - 3*x - 7 | /
Rewrite the integrand
4*x - 3 2*2*x - 3 -------------- = 1*-------------- 2 2 2*x - 3*x - 7 2*x - 3*x - 7
or
/ | | 4*x - 3 | 1*-------------- dx | 2 = | 2*x - 3*x - 7 | /
/ | | 2*2*x - 3 | -------------- dx | 2 | 2*x - 3*x - 7 | /
In the integral
/ | | 2*2*x - 3 | -------------- dx | 2 | 2*x - 3*x - 7 | /
do replacement
2 u = -3*x + 2*x
then
the integral =
/ | | 1 | ------ du = log(-7 + u) | -7 + u | /
do backward replacement
/ | | 2*2*x - 3 / 2\ | -------------- dx = log\-7 - 3*x + 2*x / | 2 | 2*x - 3*x - 7 | /
Solution is:
/ 2\ C + log\-7 - 3*x + 2*x /
The answer (Indefinite)
[src]
/ | | 4*x - 3 / 2 \ | -------------- dx = C + log\2*x - 3*x - 7/ | 2 | 2*x - 3*x - 7 | /
$$\log \left(2\,x^2-3\,x-7\right)$$
