Wolfram Alpha won't solve equation from photo

[polibuda]

TL;DR

differential equation

I have the problem with checking solution in calculators. For example wolfram doesn't give result of this equation. Have you any idea what is going on? Maybe should I simplyfy something. The equation is placed in photo.

Is y'' really multiplying y'?

Yes, I have it on my homework list.

Surely that would have been written as $6y''y'$ not $y'' \times 6y'$?

Are the other problems on your homework list second order linear ODEs?

Are you sure it isn't $y'' + 6y' + 8y = 16t^2$?

I am sure it is like I have written. Perhaps it is mistake in my homework list, so I need to contact with my teacher. Thanks for help.
