What is the coefficient of (x^2) in ( (x-1)(x-2)(x-3) )?( (x-1)(x-2)(x-3) ) में (x^2) का गुणांक क्या है?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: (-6)(-6)
The sum of constants is (1+2+3=6) and the sign is negative. Exam tip: stepwise multiplication also gives the same result.तीनों स्थिर पदों का योग (1+2+3=6) है और चिन्ह ऋणात्मक होता है। परीक्षा में क्रमिक गुणन से भी यही मिलेगा।
