Find the sum of 3x - 2y + 6 and x + 4y - 2.

Solution:

First rearrange the terms by putting together similar terms.

(3x - 2y + 6) + (x + 4y - 2)

= 3x + x - 2y + 4y + 6 - 2

 = 4x + 2y + 4

Or, we can arrange the polynomials in rows and add the terms vertically.

        3x - 2y + 6
+      x + 4y - 2
      4x + 2y + 4
