Question

Combine like terms in the expression below and select the answer choice that is equivalent. 5x + 2x2 - 3 + x - 4x2

Answer 1

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 2

Answer:

6x-7

Step-by-step explanation:

5x + x = 6x

______________

2 x 2 - 3 = 4 - 3 = 1
