सरल करने के बाद (x-3\(x^2+2\)-x-5+7x-2) की डिग्री क्या है?
After simplifying (x-3\(x^2+2\)-x-5+7x-2), what is the degree?
Explanation opens after your attempt
B. (3)
Concept
(x-3\(x^2+2\)=x-5+2x-3), and \(x^5\) cancels. The remaining \(2x^3+7x^2\) has degree (3).
Why this answer is correct
The correct answer is B. (3). (x-3\(x^2+2\)=x-5+2x-3), and \(x^5\) cancels. The remaining \(2x^3+7x^2\) has degree (3).
Exam Tip
(x-3\(x^2+2\)=x-5+2x-3) और \(x^5\) कट जाता है। बचा \(2x^3+7x^2\) है जिसकी डिग्री (3) है।
