किस व्यंजक की घात (3) है लेकिन उसमें \(x^2\) पद नहीं है?
Which expression has degree (3) but has no \(x^2\) term?
Explanation opens after your attempt
A. \(x^3-5x+6\)
Concept
In \(x^3-5x+6\), the highest power is (3) and the \(x^2\) term is absent. A missing term does not make a polynomial invalid.
Why this answer is correct
The correct answer is A. \(x^3-5x+6\). In \(x^3-5x+6\), the highest power is (3) and the \(x^2\) term is absent. A missing term does not make a polynomial invalid.
Exam Tip
\(x^3-5x+6\) में सबसे बड़ी घात (3) है और \(x^2\) पद अनुपस्थित है। अनुपस्थित पद बहुपद को अमान्य नहीं बनाता।
