यदि (q(x)=(c+5)x-3+(c-2)x-2+4x-1) की घात (2) करनी हो, तो कौन-सी शर्त चाहिए?

If (q(x)=(c+5)x-3+(c-2)x-2+4x-1) must have degree (2), what condition is needed?

Explanation opens after your attempt
Correct Answer

C. (c=-5)

Step 1

Concept

For degree (2), the coefficient of \(x^3\) must be zero. From (c+5=0), (c=-5), and the \(x^2\) coefficient (-7) remains non-zero.

Step 2

Why this answer is correct

The correct answer is C. (c=-5). For degree (2), the coefficient of \(x^3\) must be zero. From (c+5=0), (c=-5), and the \(x^2\) coefficient (-7) remains non-zero.

Step 3

Exam Tip

घात (2) के लिए \(x^3\) का गुणांक शून्य होना चाहिए। (c+5=0) से (c=-5) और \(x^2\) का गुणांक (-7) अशून्य रहता है।
