Answer:

Option B

Explanation:

Combining like terms, we get:

4 − 2x^2 − 5x + 5x^2 − 9 + 3x = (−2x^2 + 5x^2) + (−5x + 3x) + (4 − 9)

Simplifying each group of terms in parentheses, we get:

= 3x^2 − 2x − 5

Therefore, the expression that is Combining like terms, we get:

4 − 2x^2 − 5x + 5x^2 − 9 + 3x = (−2x^2 + 5x^2) + (−5x + 3x) + (4 − 9)

Simplifying each group of terms in parentheses, we get:

= 3x^2 − 2x − 5

Therefore, the expression that is equivalent to 4 − 2x^2 − 5x + 5x^2 − 9 + 3x is 3x^2 − 2x − 5. The answer is option B.
