In this question, we are asked to solve the given initial value problem by using laplace transforms.
00:06
Now, let's call the laplace transform of y, let's call it y capital.
00:13
Then, the laplace transform of dy over dt, and there is a formula for that, equals to s multiplied by y capital minus y of 0, which is 0, so it's just s multiplied by y capital.
00:28
The laplace transform of dy over dt squared by a similar formula is s squared y minus s multiplied by y of 0 minus y prime of 0.
00:46
Y of 0 is 0, so it's just s squared y minus 6.
00:52
Now, we plug that in the differential equation, we'll get s squared y capital minus 6 plus 2 multiplied by s y plus 17 y equals 0.
01:08
Now, we need to solve this equation for y.
01:11
We'll get s squared plus 2s plus 17 multiplied by y equals to 6.
01:22
From that equation, y capital equals to 6 divided by s squared plus 2s plus 17, and now we need to complete squares in the denominator...
