What is (3x2−2)+(11−5x) ?(1 point)

Question

−2x^2+9
2x^2−9
3x^2+5x−9
3x^2−5x+9

Answer 1

To simplify the expression \((3x^2 - 2) + (11 - 5x)\), we can combine the like terms step by step:

1. Start by distributing the addition: \[ 3x^2 - 2 + 11 - 5x \]

2. Combine the constant terms \(-2\) and \(11\): \[ 3x^2 - 5x + (11 - 2) = 3x^2 - 5x + 9 \]

Thus, the simplified expression is: \[ 3x^2 - 5x + 9 \]

So, the correct answer is: \[ \text{3x}^2 - 5x + 9 \]
