Solve y”+2y’+y=e^t using a power series, please show all your work and show that the answer is equivalent to c1e^-t +c2te^-t +e^t/4 once you get to the part where you have the series expansion please explain to me how you convert them into the closed form so everything makes sense to me .
I have been learning factorisation by completing the square, and then finding xFOR EXAMPLESolve for x by completing the squarex² + 10x -24 = 0= x² + 10x + 25 - 24 - 25 = 0= (x+5)² - 49 = 0= (x+5)²= 49so x = 2, or -12But this particular question has really stumped me:Solve for x by completing the square2x² - 4x - 6 = 0The answer sheet says x = -1 or 3, but I'm not sure how to get to this.
4. Find the absolute maximum value and the absolute minimum value of f(3) = 24 - 8:c2 +1 on the interval (0,3). Note: This means you should find the y-values.
