Question 1/5 Expert Mathematics Exploring Algebraic Identities Algebraic identities Class 9 Level 62

( (x-2)(x+5)(x-7) ) में \(x^2\) का गुणांक क्या होगा?

What will be the coefficient of \(x^2\) in ( (x-2)(x+5)(x-7) )?

Explanation opens after your attempt
Correct Answer

A. (-4)

Step 1

Concept

In three linear factors, the coefficient of \(x^2\) is the sum of constants. Here (-2+5-7=-4).

Step 2

Why this answer is correct

The correct answer is A. (-4). In three linear factors, the coefficient of \(x^2\) is the sum of constants. Here (-2+5-7=-4).

Step 3

Exam Tip

तीन रैखिक गुणनखंडों में \(x^2\) का गुणांक स्थिर संख्याओं का योग होता है। यहाँ (-2+5-7=-4) है।

Question 2/5 Hard Mathematics Exploring Algebraic Identities Algebraic identities Class 9 Level 64

( (x+1)(x+2)(x+3) ) के प्रसार में \(x^2\) का गुणांक क्या है?

What is the coefficient of \(x^2\) in the expansion of ( (x+1)(x+2)(x+3) )?

Explanation opens after your attempt
Correct Answer

C. (6)

Step 1

Concept

For three linear factors, the coefficient of \(x^2\) is (1+2+3=6). Exam tip: you can also check by expanding the first two factors.

Step 2

Why this answer is correct

The correct answer is C. (6). For three linear factors, the coefficient of \(x^2\) is (1+2+3=6). Exam tip: you can also check by expanding the first two factors.

Step 3

Exam Tip

तीन रैखिक पदों में \(x^2\) का गुणांक (1+2+3=6) होता है। परीक्षा में पहले दो पदों को खोलकर भी जाँच सकते हैं।

Question 3/5 Easy Mathematics Exploring Algebraic Identities Algebraic identities Class 9 Level 66

( (3x+4)2 ) में \(x^2\) का गुणांक क्या है?

What is the coefficient of \(x^2\) in ( (3x+4)2 )?

Explanation opens after your attempt
Correct Answer

C. (9)

Step 1

Concept

( (3x)2=9x-2 ). Exam tip: square the whole (3x).

Step 2

Why this answer is correct

The correct answer is C. (9). ( (3x)2=9x-2 ). Exam tip: square the whole (3x).

Step 3

Exam Tip

( (3x)2=9x-2 ) है। परीक्षा में (3x) का पूरा वर्ग लें।

Question 4/5 Easy Mathematics Exploring Algebraic Identities Algebraic identities Class 9 Level 66

\( x^2-49 \) को गुणनखंड रूप में लिखिए।

Write \( x^2-49 \) in factor form.

Explanation opens after your attempt
Correct Answer

B. ( (x+7)(x-7) )

Step 1

Concept

Since \(49=7^2\), \(x^2-49=x^2-7^2\). Exam tip: identify squares first.

Step 2

Why this answer is correct

The correct answer is B. ( (x+7)(x-7) ). Since \(49=7^2\), \(x^2-49=x^2-7^2\). Exam tip: identify squares first.

Step 3

Exam Tip

\(49=7^2\), इसलिए \(x^2-49=x^2-7^2\) है। परीक्षा में वर्ग पहचानना जरूरी है।

( (5x)2 ) का मान क्या है?

What is the value of ( (5x)2 )?

Explanation opens after your attempt
Correct Answer

C. \(25x^2\)

Step 1

Concept

( (5x)2=25x-2 ). Exam tip: square both the coefficient and the variable.

Step 2

Why this answer is correct

The correct answer is C. \(25x^2\). ( (5x)2=25x-2 ). Exam tip: square both the coefficient and the variable.

Step 3

Exam Tip

( (5x)2=25x-2 ) होता है। परीक्षा में गुणांक और चर दोनों का वर्ग करें।
