Question 499453
you can add the x squared terms together, the x terms together and the constant terms together.  In order to add fractions you need to get a common denominator, so 2/3 + 1/6 would need to be 4/6 + 1/6=5/6
-1/3 + 1/2 = -2/6 +3/6 =1/6, so your x^2 term will be {{{(1/6)x^2}}}
Do this with the other terms as well. Be careful though when you subtract, because you will need to distribute the negative throughout the parenthesis and then combine the like terms.
