To simplify the expression 3k + 43k² + 5k + 3 using the vertical method, we start by rearranging the terms based on their degrees.
Now, write the like terms vertically:
43k² 3k 5k 3
Now, we can combine the like terms:
- The k² term is just 43k².
- The k terms are 3k and 5k, which combine to give us 8k.
- The constant term is simply 3.
Putting it all together, we get:
43k² + 8k + 3
Thus, the simplified expression is 43k² + 8k + 3.
