00:00:00.000 --> 00:00:04.412
Here is the problem: 2x/3 plus x/6.

2
00:00:04.862 --> 00:00:07.648
Simplify the polynomial expression in x.

3
00:00:08.448 --> 00:00:09.667
Read the expression.

4
00:00:10.117 --> 00:00:20.961
Combine like terms. x: 2 over 3 plus 1 over 6 equals 5 over 6. Like terms have identical variables and exponents, so only their coefficients are added.

5
00:00:21.411 --> 00:00:26.032
Write the result in standard form. Terms are ordered by descending total degree.

6
00:00:26.832 --> 00:00:29.235
So the answer is (5 over 6)x.

7
00:00:29.685 --> 00:00:37.510
After expanding and combining like terms the expression is (5 over 6)x, a polynomial of degree 1 with 1 term.

8
00:00:38.310 --> 00:00:53.078
Spot check at x equals 0.73: original 0.6083333333, simplified 0.6083333333, which checks out.
