2. Consider the equation: dy = y² + 2yt +t² - 2y – 2t – 1 dt a. Find a change of variable that transforms the equation into an autonomous equation change of variable: new equation: b. Sketch the phase line for the resulting equation and use it to sketch graphs of the long-term behaviors of all the qualitatively different solutions for the new variable, and then for the original equation.

3 Solve for x: 1. х 16 28

Solve the following equation. X+5 2 x+3 x+3 Select the correct choice below and, if necessary, fill in the answer box to complete your choice. O A. The solution set is { (Type an integer or a simplified fraction. Use a comma to separate answers as needed.) O B. The solution set is ø.

I'm not sure what I'm doing wrong to find this answer.  I've tried 4 and 8 as the LCD but the answer I get doesn't fit for x.
