Such an equation cannot be solved. There must be an equal sign for it to have solutions.
However, it can be factorised.
By inspection through the factor theorem, I found that 2y - 1 is a factor.
Through long division, I get:
18y^3 - 33y^2 + 2y +5=(2y+1)(9y^2-12y-5)
You can factor the quadratic now. :)
