What is the correct expansion of (x − 6)²?(x − 6)² का सही विस्तार क्या है?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: x² − 12x + 36x² − 12x + 36
Using (a − b)² = a² − 2ab + b² with a = x and b = 6 gives (x − 6)² = x² − 2(x)(6) + 6² = x² − 12x + 36. Therefore, option A is correct.(a − b)² = a² − 2ab + b² के सूत्र में a = x और b = 6 रखने पर (x − 6)² = x² − 2(x)(6) + 6² = x² − 12x + 36 मिलता है। इसलिए विकल्प A सही है।
