Expert Mathematics Polynomials Class 10 Level 46

यदि बहुपद (p(x)=kx-3+2x-2-3x+1) वास्तव में द्विघात बहुपद है, तो (k) का मान क्या होगा?

If (p(x)=kx-3+2x-2-3x+1) is actually a quadratic polynomial, what must be the value of (k)?

Explanation opens after your attempt
Correct Answer

A. (0)

Step 1

Concept

For it to be quadratic, the coefficient of \(x^3\) must be (0), while the coefficient of \(x^2\) is non-zero. Focus on the leading non-zero term.

Step 2

Why this answer is correct

The correct answer is A. (0). For it to be quadratic, the coefficient of \(x^3\) must be (0), while the coefficient of \(x^2\) is non-zero. Focus on the leading non-zero term.

Step 3

Exam Tip

द्विघात होने के लिए \(x^3\) का गुणांक (0) होना चाहिए और \(x^2\) का गुणांक अशून्य है। घात पहचानते समय प्रमुख पद पर ध्यान दें।
