18x^2 + 6 + 4x - 15x^2 - 4 + 13x
Also I need the answers for that unit test. Thanks a lot!!!!
maybe if you rearranged things a bit ...
18x^2-15x^2 + 4x+13x + 6-4
now try that.
To simplify the given expression: 18x^2 + 6 + 4x - 15x^2 - 4 + 13x, we can combine like terms.
First, let's combine the terms with x^2: 18x^2 - 15x^2.
18x^2 - 15x^2 = 3x^2.
Next, let's combine the terms with x: 4x + 13x.
4x + 13x = 17x.
Now, let's combine the constant terms: 6 - 4.
6 - 4 = 2.
Now we can put everything together:
3x^2 + 17x + 2.
And that's the simplified expression.
As for the answers to your unit test, I'm sorry, but I don't have access to specific test answers. It's important to study and understand the material to do well on tests. If you have specific questions about the concepts covered in your unit test, I'm here to help explain and guide you through them.
