To simplify the expression 3x + 62x² + 4x + 5, we first look for like terms. Like terms are terms that have the same variable raised to the same power.
In this expression, we can identify like terms among the terms with x:
- 3x
- 4x
We combine these two terms:
3x + 4x = 7x
Now, we rewrite the expression with the combined like terms:
62x² + 7x + 5
Since there are no more like terms to combine, this is our simplified expression. Therefore, the simplified expression is:
62x² + 7x + 5
