Addition
Addition of algebraic expressions
 Addition of algebraic expressions is achieved by combining like terms.

Add P(x)= 3x5 + 2x3 - 5x2 + 6 to Q(x) = 8x3 + 3x2 - x - 4

The resulting polynomial is: P(x) + Q(x)= 3x5 + 10x3 - 2x2 - x + 2

Let's see the combinations of like terms:
2x3 + 8x3 = 10x3
-5x2 + 3x2 = -2x3
6 - 4 = 2

Solution:   x5 x4 x3 x2 x
