00:00:00.000 --> 00:00:03.843
Here is the problem: (1 over 2)x plus (1 over 3)x.

2
00:00:04.293 --> 00:00:07.207
Simplify the polynomial expression in x.

3
00:00:08.007 --> 00:00:09.238
Read the expression.

4
00:00:09.688 --> 00:00:20.532
Combine like terms. x: 1 over 2 plus 1 over 3 equals 5 over 6. Like terms have identical variables and exponents, so only their coefficients are added.

5
00:00:20.982 --> 00:00:25.614
Write the result in standard form. Terms are ordered by descending total degree.

6
00:00:26.414 --> 00:00:28.736
So the answer is (5 over 6)x.

7
00:00:29.186 --> 00:00:36.965
After expanding and combining like terms the expression is (5 over 6)x, a polynomial of degree 1 with 1 term.

8
00:00:37.765 --> 00:00:52.208
Spot check at x equals 0.73: original 0.6083333333, simplified 0.6083333333, which checks out.
