Let's simplify step-by-step.
5x + 2x^2 − 3 + x − 4x^2
=5x + 2x^2 + −3 + x + −4x^2
Combine Like Terms:
=5x + 2x^2 + −3 + x + −4x^2
=(2x^2 + −4x^2)+(5x + x) + (−3)
=−2x^2+ 6x + −3
Answer:
6x-7
Step-by-step explanation:
5x + x = 6x
______________
2 x 2 - 3 = 4 - 3 = 1
1 - 4 x 2 = 1 - 8 = -7
______________
6x - 7
