Question 1/50 Hard Mathematics Exploring Algebraic Identities Quadratic expressions Class 9 Level 74

((x-1)(x-9)) और ((x-5)2) में कौन सा संबंध सही है?

Which relation is correct between ((x-1)(x-9)) and ((x-5)2)?

Explanation opens after your attempt
Correct Answer

B. ((x-5)2) पहले से (16) अधिक है((x-5)2) is greater than the first by (16)

Explanation

Simple Explanation

((x-1)(x-9)=x-2-10x+9) और ((x-5)2=x-2-10x+25) है। परीक्षा में समान पद हटाकर स्थिर पदों की तुलना करें। / ((x-1)(x-9)=x-2-10x+9) and ((x-5)2=x-2-10x+25). Exam tip: remove common terms and compare constants.

Question 2/50 Hard Mathematics Exploring Algebraic Identities Quadratic expressions Class 9 Level 74

यदि \(x+\frac{2}{x}=6\) हो तो \(x^2+\frac{4}{x^2}\) का मान क्या होगा?

If \(x+\frac{2}{x}=6\), what is the value of \(x^2+\frac{4}{x^2}\)?

Explanation opens after your attempt
Correct Answer

C. (32)

Explanation

Simple Explanation

वर्ग करने पर \(x^2+4+\frac{4}{x^2}=36\) है इसलिए मान (32) है। परीक्षा में (2ab) पद (4) घटाएं। / Squaring gives \(x^2+4+\frac{4}{x^2}=36\), so the value is (32). Exam tip: subtract the (2ab) term (4).

Explanation opens after your attempt
Correct Answer

A. (6)

Explanation

Simple Explanation

अंतर (3x-2+2x-5-\(x^2-4x+7\)=2x-2+6x-12) है। परीक्षा में घटाते समय कोष्ठक के चिह्न बदलें। / The difference is (3x-2+2x-5-\(x^2-4x+7\)=2x-2+6x-12). Exam tip: change signs inside the bracket while subtracting.

What is the simplified form of ((2x+5)2-(2x-5)2)?

Explanation opens after your attempt
Correct Answer

D. (40x)

Explanation

Simple Explanation

((a+b)2-(a-b)2=4ab) में (a=2x) और (b=5) रखने पर (40x) मिलता है। परीक्षा में पहचान सीधे लगाएं। / Using ((a+b)2-(a-b)2=4ab) with (a=2x) and (b=5) gives (40x). Exam tip: apply the identity directly.

Question 5/50 Hard Mathematics Exploring Algebraic Identities Quadratic expressions Class 9 Level 74

यदि \(x^2+px+36\) पूर्ण वर्ग है और (p) ऋणात्मक है तो (p) का मान क्या होगा?

If \(x^2+px+36\) is a perfect square and (p) is negative, what will be the value of (p)?

Explanation opens after your attempt
Correct Answer

C. (-12)

Explanation

Simple Explanation

\(36=6^2\) है और ऋण मध्य पद \(-2\cdot6\cdot x=-12x\) होगा। परीक्षा में शर्त के अनुसार चिह्न चुनें। / Since \(36=6^2\), the negative middle term is \(-2\cdot6\cdot x=-12x\). Exam tip: choose the sign according to the condition.

Question 6/50 Hard Mathematics Exploring Algebraic Identities Quadratic expressions Class 9 Level 74

\(x^2+2x+5\) को ((x+a)2+b) के रूप में लिखने पर (a+b) कितना होगा?

When \(x^2+2x+5\) is written in the form ((x+a)2+b), what is (a+b)?

Explanation opens after your attempt
Correct Answer

B. (5)

Explanation

Simple Explanation

(x-2+2x+5=(x+1)2+4) है इसलिए (a+b=5) है। परीक्षा में पूर्ण वर्ग पूरा करके शेष स्थिर पद जोड़ें। / (x-2+2x+5=(x+1)2+4), so (a+b=5). Exam tip: complete the square and add the remaining constant.

What is the sum of the values of \(x^2-2x+1\) at (x=0) and (x=2)?

Explanation opens after your attempt
Correct Answer

C. (2)

Explanation

Simple Explanation

(x=0) पर मान (1) और (x=2) पर मान (1) है इसलिए योग (2) है। परीक्षा में दोनों मान अलग निकालकर जोड़ें। / At (x=0), the value is (1), and at (x=2), the value is (1), so the sum is (2). Exam tip: find both values separately and add.
