$\displaystyle -12-2 = -14$ so that's the middle bracket sorted. Also you can take a factor of y from the first set.

$\displaystyle -14y(4y^2+5y-12)(7y^2-9y+12)$

Since this gives a polynomial of order 5 whereas the book says order 6 I suspect you've made a typo in the original question. Probably the middle bracket
