What is the value of ( (x+4)(x+10)-(x+6)(x+8) )?( (x+4)(x+10)-(x+6)(x+8) ) का मान क्या है?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: (-8)सही मान
Both expansions have the same (x^2+14x), and constants give (40-48=-8). Exam tip: cancel like terms and subtract constants.दोनों विस्तारों में (x^2+14x) समान है और स्थिर पद (40-48=-8) देता है। परीक्षा में समान पद काटकर स्थिर पद घटाएँ।
