Question 1110294
----------------------
y=x2+6x-2x+2x2-18+4
---------------------


Write it properly.
---------------------
y=x^2+6x-2x+2x^2-18+4
---------------------


That should appeared when in 'normal' notation like this:
----------------------------
{{{y=x^2+6x-2x+2x^2-18+4}}}
----------------------------


SIMPLIFY the equation.
---------------------------
{{{y=3x^2+4x-14}}}
---------------------------


Next, you need to have a question you want help answering.  What do you want with the equation?
