\(x^2-bx+18\) के गुणनखंड ((x-3)(x-6)) हैं। (b) क्या है?
The factors of \(x^2-bx+18\) are ((x-3)(x-6)). What is (b)?
Explanation opens after your attempt
C. (9)correct value
Concept
((x-3)(x-6)=x-2-9x+18), so (b=9). In exams (b) remains positive because the expression has (-bx).
Why this answer is correct
The correct answer is C. (9) / correct value. ((x-3)(x-6)=x-2-9x+18), so (b=9). In exams (b) remains positive because the expression has (-bx).
Exam Tip
((x-3)(x-6)=x-2-9x+18), इसलिए (b=9) है। परीक्षा में ऋण चिन्ह के कारण (b) धनात्मक रहता है।
