\(x^2-19x+90=0\) के गुणनखंड कौनसे होंगे?

What will be the factors of \(x^2-19x+90=0\)?

Explanation opens after your attempt
Correct Answer

A. ((x-9)(x-10))

Step 1

Concept

(9+10=19) and \(9\times10=90\), so ((x-9)(x-10)) is correct. In exams, take both negative signs for a negative middle term.

Step 2

Why this answer is correct

The correct answer is A. ((x-9)(x-10)). (9+10=19) and \(9\times10=90\), so ((x-9)(x-10)) is correct. In exams, take both negative signs for a negative middle term.

Step 3

Exam Tip

(9+10=19) और \(9\times10=90\), इसलिए ((x-9)(x-10)) सही है। परीक्षा में ऋणात्मक मध्य पद के लिए दोनों ऋणात्मक चिन्ह लें।

\(x^2-13x+40=0\) के गुणनखंड कौनसे होंगे?

What will be the factors of \(x^2-13x+40=0\)?

Explanation opens after your attempt
Correct Answer

A. ((x-5)(x-8))

Step 1

Concept

(5+8=13) and \(5\times8=40\), so ((x-5)(x-8)) is correct. In exams, take both negative signs for a negative middle term.

Step 2

Why this answer is correct

The correct answer is A. ((x-5)(x-8)). (5+8=13) and \(5\times8=40\), so ((x-5)(x-8)) is correct. In exams, take both negative signs for a negative middle term.

Step 3

Exam Tip

(5+8=13) और \(5\times8=40\), इसलिए ((x-5)(x-8)) सही है। परीक्षा में ऋणात्मक मध्य पद के लिए दोनों ऋणात्मक चिन्ह लें।

Question Easy Mathematics Quadratic Equations Methods of Solving Quadratic Equations Class 10 Level 34

\(x^2-8x+15=0\) के गुणनखंड कौनसे होंगे?

What will be the factors of \(x^2-8x+15=0\)?

Explanation opens after your attempt
Correct Answer

A. ((x-3)(x-5))

Step 1

Concept

(3+5=8) and \(3\times5=15\), so with signs we get ((x-3)(x-5)). In exams, for a negative middle term, look for both negative factors.

Step 2

Why this answer is correct

The correct answer is A. ((x-3)(x-5)). (3+5=8) and \(3\times5=15\), so with signs we get ((x-3)(x-5)). In exams, for a negative middle term, look for both negative factors.

Step 3

Exam Tip

(3+5=8) और \(3\times5=15\), इसलिए संकेतों के साथ ((x-3)(x-5)) मिलता है। परीक्षा में ऋणात्मक मध्य पद के लिए दोनों ऋणात्मक गुणनखंड देखें।
