Math Focus: Mainly analysis and algebra
I can't even understand what your answer means. What is $\sin(6x -- \sqrt{})$? It's syntactically meaningless.

As Country Boy suggests, post your working so that we can see where your approach is incorrect.

y = C1*cos(√6x) + C2*sin(√6x) - (7x² - 4x + (17/21))e^(6x)
