aur yeh ek aasan sa prashn ban jayega. dono terms(7z^2 or 7z) 7z se divisible hain to 7z ko bahar nikal letein hain to numerator = 7z(z+1) to numerator = 7z(z+1) to numerator = 7z(z+1) to numerator = 7z(z+1) agar tum multiply karke bracket khol dete hon to tumhe 7z squared plus 7z ( 7z^2 + 7z) milta hai jab tum fractions multiply karte hon, to ye sirf numerator times the numerator ,over denominator times the denominator hota hai to 7z(z+1) times the numerator z squared minus 4 (z^2-4), jo ki (a^2-b^2) ke form mein hai to z^2-4 = (z-2)(z+2) . to z^2-4 = (z-2)(z+2) , asha karta hoon tumhe ye pahchan pa rahe ho es samhe par ab denominator pe dhyan deten hain 4 ko bahar nikal lete hain, to yeh 4 times (z+2) ho jata hai.
og det vil blive til et temmelig pænt problem. lad os se, begge disse udtryk er dividerbart med 7z. so lad os faktorisere dette ud.
