सरल करने के बाद \(4x^3-4x^3+9x^2-5\) की डिग्री क्या होगी?
After simplifying \(4x^3-4x^3+9x^2-5\), what will be the degree?
Explanation opens after your attempt
B. (2)
Concept
Since \(4x^3-4x^3=0\), \(9x^2-5\) remains. Its degree is (2).
Why this answer is correct
The correct answer is B. (2). Since \(4x^3-4x^3=0\), \(9x^2-5\) remains. Its degree is (2).
Exam Tip
\(4x^3-4x^3=0\) होने से \(9x^2-5\) बचता है। इसकी डिग्री (2) है।
