The correct answer is B. (4). When (c=0), the \(x^5\) term disappears and the coefficient of \(x^4\) remains (1). Therefore the degree is (4).
Step 3
Exam Tip
(c=0) होने पर \(x^5\) पद हट जाता है और \(x^4\) का गुणांक (1) रहता है। इसलिए डिग्री (4) है।

To become constant, both (v+1=0) and (v-2=0) are required. One value of (v) cannot satisfy both conditions.
Step 2
Why this answer is correct
The correct answer is D. कभी नहीं / Never. To become constant, both (v+1=0) and (v-2=0) are required. One value of (v) cannot satisfy both conditions.
Step 3
Exam Tip
नियतांक बनने के लिए (v+1=0) और (v-2=0) दोनों चाहिए। एक ही (v) दोनों शर्तें पूरी नहीं कर सकता।

A \(4x^2-9\)
B \(4x^2+x-9\)
C (4x-9)
D \(x^3+4x^2-9\)
Explanation opens after your attempt
Correct Answer
A. \(4x^2-9\)
Step 1
Concept
\(4x^2-9\) has degree (2), and the (x) term is absent. So the coefficient of (x) is (0).
Step 2
Why this answer is correct
The correct answer is A. \(4x^2-9\). \(4x^2-9\) has degree (2), and the (x) term is absent. So the coefficient of (x) is (0).
Step 3
Exam Tip
\(4x^2-9\) की डिग्री (2) है और (x) पद अनुपस्थित है। इसलिए (x) का गुणांक (0) है।

? Hint Small clue
A \(x^3+x+2\)
B \(x^3+x-2\)
C \(x^2+x+2\)
D \(x^3+2\)
Explanation opens after your attempt
Correct Answer
A. \(x^3+x+2\)
Step 1
Concept
\(\frac{x^2-4}{x-2}=x+2\) when \(x\neq2\). Therefore the simplified form is \(x^3+x+2\).
Step 2
Why this answer is correct
The correct answer is A. \(x^3+x+2\). \(\frac{x^2-4}{x-2}=x+2\) when \(x\neq2\). Therefore the simplified form is \(x^3+x+2\).
Step 3
Exam Tip
\(\frac{x^2-4}{x-2}=x+2\) जब \(x\neq2\)। इसलिए सरल रूप \(x^3+x+2\) है।
