Question 1/3 Easy Mathematics Quadratic Equations Introduction to Quadratic Equations Class 10 Level 29

समीकरण \(x^2-13x=0\) में कौन सा पद अनुपस्थित है?

Which term is absent in \(x^2-13x=0\)?

Explanation opens after your attempt
Correct Answer

C. स्थिर पदConstant term

Step 1

Concept

It can be written as \(x^2-13x+0=0\). So the constant term is absent.

Step 2

Why this answer is correct

The correct answer is C. स्थिर पद / Constant term. It can be written as \(x^2-13x+0=0\). So the constant term is absent.

Step 3

Exam Tip

इसे \(x^2-13x+0=0\) लिखा जा सकता है। इसलिए स्थिर पद अनुपस्थित है।

Explanation opens after your attempt
Correct Answer

C. स्थिर पदConstant term

Step 1

Concept

It is treated as \(x^2+10x+0=0\). So the constant term is absent.

Step 2

Why this answer is correct

The correct answer is C. स्थिर पद / Constant term. It is treated as \(x^2+10x+0=0\). So the constant term is absent.

Question 3/3 Medium Mathematics Polynomials Geometrical meaning of the zeroes of a polynomial. Class 10 Level 22

किस स्थिति में रैखिक बहुपद का कोई वास्तविक शून्यक नहीं होगा?

In which situation will a linear polynomial have no real zero?

Explanation opens after your attempt
Correct Answer

B. जब उसका ग्राफ (x)-अक्ष के समांतर और ऊपर होWhen its graph is parallel to and above the (x)-axis

Step 1

Concept

A line parallel to and above the (x)-axis does not meet the (x)-axis. Tip: such a graph behaves like a non-zero constant polynomial.

Step 2

Why this answer is correct

The correct answer is B. जब उसका ग्राफ (x)-अक्ष के समांतर और ऊपर हो / When its graph is parallel to and above the (x)-axis. A line parallel to and above the (x)-axis does not meet the (x)-axis. Tip: such a graph behaves like a non-zero constant polynomial.

Step 3

Exam Tip

(x)-अक्ष के समांतर ऊपर रेखा (x)-अक्ष से नहीं मिलती। टिप: ऐसा ग्राफ अशून्य स्थिर बहुपद जैसा होता है।
