What does the picture show?
This picture shows an equation of combining like terms. The equation seen above has been solved wrong but the words in red go through the correct process.
What the viewer needs to pay close attention to in order to understand the concept?
The viewer needs to pay close attention to what the mistake of the student was. The mistake he made was combining all the terms together even though they weren't alike. They combined the numbers and placed the exponent along with the X.
Correction: What the student had to do was combine like terms of the problem which were the numbers with the exponent of x^4(10x^4 & 8x^4). Then they just bring down the 12x^5 to what we had combined and the correct answer would be 12x^5+18x^4.

When I looked at the picture I could instantly see the mistake. This problem could be easily solved, but he made a cheeses bucket mistake!!
