Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: (4)(4)
The first is (x^2+6x+9) and the second is (x^2+6x-7). Subtracting gives (9-(-7)=16), so the correct option should be (16).पहला (x^2+6x+9) और दूसरा (x^2+6x-7) है। घटाने पर (16) नहीं बल्कि (9-(-7)=16) होगा इसलिए सही विकल्प (16) होना चाहिए।
