Question 1/5 Medium Mathematics Quadratic Equations Introduction to Quadratic Equations Class 10 Level 29

किस विकल्प में (x) पद अनुपस्थित है लेकिन समीकरण द्विघात है?

In which option is the (x) term absent but the equation is quadratic?

Explanation opens after your attempt
Correct Answer

A. \(3x^2-27=0\)

Step 1

Concept

In \(3x^2-27=0\), the \(x^2\) term is present and the (x) term is absent. An equation can be quadratic even without the (x) term.

Step 2

Why this answer is correct

The correct answer is A. \(3x^2-27=0\). In \(3x^2-27=0\), the \(x^2\) term is present and the (x) term is absent. An equation can be quadratic even without the (x) term.

Step 3

Exam Tip

\(3x^2-27=0\) में \(x^2\) पद है और (x) पद अनुपस्थित है। (x) पद न होने पर भी समीकरण द्विघात हो सकता है।

Question 2/5 Medium Mathematics Quadratic Equations Introduction to Quadratic Equations Class 10 Level 28

किस विकल्प में द्विघात समीकरण का (x) वाला पद अनुपस्थित है लेकिन समीकरण द्विघात है?

In which option is the (x) term absent but the equation is still quadratic?

Explanation opens after your attempt
Correct Answer

A. \(x^2-49=0\)

Step 1

Concept

In \(x^2-49=0\), the \(x^2\) term is present and the (x) term is absent. An equation can be quadratic even without an (x) term.

Step 2

Why this answer is correct

The correct answer is A. \(x^2-49=0\). In \(x^2-49=0\), the \(x^2\) term is present and the (x) term is absent. An equation can be quadratic even without an (x) term.

Step 3

Exam Tip

\(x^2-49=0\) में \(x^2\) पद है और (x) पद अनुपस्थित है। (x) पद न होने पर भी समीकरण द्विघात हो सकता है।

Question 3/5 Easy Mathematics Quadratic Equations Introduction to Quadratic Equations Class 10 Level 30

समीकरण \(2x^2+5=0\) में कौन-सा पद अनुपस्थित है?

Which term is absent in \(2x^2+5=0\)?

Explanation opens after your attempt
Correct Answer

C. रैखिक पदLinear term

Step 1

Concept

There is no (x) term, so the linear term is absent. The coefficient of a missing term is considered (0).

Step 2

Why this answer is correct

The correct answer is C. रैखिक पद / Linear term. There is no (x) term, so the linear term is absent. The coefficient of a missing term is considered (0).

Step 3

Exam Tip

इसमें (x) वाला पद नहीं है इसलिए रैखिक पद अनुपस्थित है। अनुपस्थित पद का गुणांक (0) माना जाता है।

Question 4/5 Easy Mathematics Quadratic Equations Introduction to Quadratic Equations Class 10 Level 29

समीकरण \(13x^2-20=0\) में (b) का मान क्या है?

What is the value of (b) in \(13x^2-20=0\)?

Explanation opens after your attempt
Correct Answer

B. (0)

Step 1

Concept

We write it as \(13x^2+0x-20=0\). So (b=0).

Step 2

Why this answer is correct

The correct answer is B. (0). We write it as \(13x^2+0x-20=0\). So (b=0).

Step 3

Exam Tip

इसे \(13x^2+0x-20=0\) लिखते हैं। इसलिए (b=0) है।

Question 5/5 Easy Mathematics Quadratic Equations Introduction to Quadratic Equations Class 10 Level 28

समीकरण \(9x^2+11=0\) में \(x\) का मान क्या है?

What is the value of \(x\) in \(9x^2+11=0\)?

Explanation opens after your attempt
Correct Answer

C. (0)

Step 1

Concept

It is written as \(9x^2+0x+11=0\). So \(x=0\).

Step 2

Why this answer is correct

The correct answer is C. (0). It is written as \(9x^2+0x+11=0\). So \(x=0\).

Step 3

Exam Tip

इसे \(9x^2+0x+11=0\) लिखा जाता है। इसलिए \(x=0\) है।
