For degree (3), the \(x^4\) coefficient must be zero and the \(x^3\) coefficient must be non-zero. At (a=2), \(a^2-4=0\) and (a+2=4).
Step 2
Why this answer is correct
The correct answer is B. (2). For degree (3), the \(x^4\) coefficient must be zero and the \(x^3\) coefficient must be non-zero. At (a=2), \(a^2-4=0\) and (a+2=4).
Step 3
Exam Tip
घात (3) के लिए \(x^4\) का गुणांक शून्य और \(x^3\) का गुणांक अशून्य होना चाहिए। (a=2) पर \(a^2-4=0\) और (a+2=4) है।
The coefficient of \(x^3\) is always non-zero. Therefore, the degree remains (3) for every (h).
Step 2
Why this answer is correct
The correct answer is B. कोई भी वास्तविक (h) / Any real (h). The coefficient of \(x^3\) is always non-zero. Therefore, the degree remains (3) for every (h).
Step 3
Exam Tip
\(x^3\) का गुणांक (2) हमेशा अशून्य है। इसलिए घात (3) हर (h) के लिए रहेगी।
The coefficient of \(x^3\) is (2), which is never zero. So the degree remains (3) for every (h).
Step 2
Why this answer is correct
The correct answer is B. कोई भी वास्तविक (h) / Any real (h). The coefficient of \(x^3\) is (2), which is never zero. So the degree remains (3) for every (h).
Step 3
Exam Tip
\(x^3\) का गुणांक (2) है जो कभी शून्य नहीं होता। इसलिए घात (3) हर (h) के लिए रहेगी।
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.
Step 2
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.
Step 3
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।
