Yes, you add and subtract them just like real numbers.

To add polynomials, you must clear the parenthesis, combine and add the like terms. In some cases you will need to remember the order of operations. Remember, when adding and subtracting like parts, the variable never changes. Here are a couple of examples: (5x + 7y) + (2x - 1y) = 5x + 7y + 2x - 1y ----- (Clear the parenthesis) =5x + 2x + 7y - 1y ----- (Combine the like terms) = 7x + 6y --- (Add like terms) Another Example: (y2 - 3y + 6) + (y - 3y 2 + y3) y2 - 3y + 6+ y - 3y2 + y3 ---- (Clear the parenthesis) y3 + y2 - 3y2 - 3y + y + 6----- (Combine the like terms) y3 - 2y2 - 2y + 6---- (Add like terms) Subtracting Polynomials To subtract polynomials, you must change the sign of terms being subtracted, clear the parenthesis, and combine the like terms. Here's an example: (4x2 - 4) - (x2 + 4x - 4) (4x2 - 4) + (-x2 - 4x + 4) ---- (Change the signs) 4x2 - 4 + -x2 - 4x + 4 ---- (Clear the parenthesis) 4x2 -x2 - 4x- 4 + 4 -- ----- (Combine the like terms) 3x2 - 4x Another Example: (5x2 + 2x +1) - ( 3x2 – 4x –2 ) 5x2 + 2x +1 - 3x2 + 4x +2 --(Change the signs and clear the parenthesis) 5x2 - 3x2 + 2x+ 4x+1 + 2 --(Combine the like terms) 2x2+ 6x +3

Can you type out the polynomials that you want to add? The whole idea is to add "similar" terms.
