Question

¿Me pueden ayudar con estos ejercicios de integrales por favor? Es urgente :'(

Answer 1

$-1\int _{\left(2w+3\right)^2dw}^0\:$
$-1\cdot \int _{\left(2w+3\right)^2dw}^01dd$
$=-1\cdot \left(-w\left(2w+3\right)^2d\right)$
$=dw\left(2w+3\right)^2$

$3\int _{\left(\frac{x^2-1}{x-1}\right)dx}^2\:$
$3\cdot \int _{\left(\frac{x^2-1}{x-1}\right)dx}^21dd$
$=3\left(2-x\left(x+1\right)d\right)$


$1\int _{\left(\frac{2x^3-4x^2+5}{x^2}\right)dx}^3\:$
$1\cdot \int _{\left(\frac{2x^3-4x^2+5}{x^2}\right)dx}^31dd$
$=1\cdot \left(\frac{\left(-2\left(x-2\right)x^2-5\right)d}{x}+3\right)$
$=\frac{d\left(-2\left(x-2\right)x^2-5\right)}{x}+3$
