Question 71976: Simplify (2x2 - 4x + 6)+(2x2 + 4x - 6)
All work needed to arrive at a correct answer. If it is not a question that requires work, you will need to provide a complete explanation of how you determined the correct answer. (Explanations for those problems not requiring work must demonstrate your understanding of the concept.)
The correct answer

You can put this solution on YOUR website!
Simplify (2x^2 - 4x + 6)+(2x^2 + 4x - 6)
Add "like" terms to get:
=4x^2
The -4x and +4x add to zero
The 6 and -6 add to zero
So the answer is 4x^2
