Observe that $(x^2+2x+2)'=2x+2$ .

You have that $\int \frac{2x}{x^2+2x+2}\; dx=\int \frac{2x+2-2}{x^2+2x+2}\; dx=\int \frac{2x+2}{x^2+2x+2}\; dx+\int \frac{1}{x^2+2x+2}\; dx=I_1+2I_2$ .

To compute $I_1$ you set $y=x^2+2x+2$ , so $dy=2x+2\; dx$ . Therefore, $I_1=\int \frac{1}{y}\; dy=\ln |y|=\ln |x^2+2x+2|=\ln (x^2+2x+2)$ .

For $I_2$ observe that $x^2+2x+2=(x+1)^2+1$ . Let $y=x+1$ . Then $dy=dx$ and $I_2=\int \frac{1}{y^2+1}=\arctan y=\arctan (x+1)$ .

So, $\int \frac{2x}{x^2+2x+2}=\ln (x^2+2x+2)+2\arctan (x+1)+c$ .

5 solutions.

Step-by-step explanation:

so first we have to do this using the theorum we find all the divors of -2

so +-2, +-1/ +-2,+-1,+-4 so there would be 5 solutions.

+- 1/4,1/2,1,2,4

Convert 375 minutes to hours?

Makovka662 [10]

Answer:

6.25 hours

Step-by-step explanation:

As we know that,

1 hour = 60 minutes

⇒ $1 \ minute = \frac{1}{60} \ hour$

⇒ $375 \ minutes =375\times \frac{1}{60} \ hours$

⇒ 375 mintes = 6.25 hours

Thus, 375 mintes = 6.25 hours
