Correct Answer

C. \(-3x^2\)

Step 1

Concept

The coefficients are (2+(-5)=-3), and the variable part \(x^2\) stays the same. So the sum is \(-3x^2\).

Step 2

Why this answer is correct

The correct answer is C. \(-3x^2\). The coefficients are (2+(-5)=-3), and the variable part \(x^2\) stays the same. So the sum is \(-3x^2\).

Step 3

Exam Tip

गुणांक (2+(-5)=-3) हैं और चर भाग \(x^2\) वही रहता है। इसलिए योग \(-3x^2\) है।
