{(481 + 426)2 - 4 x 481 x 426} = ? Choices:
A) 3025
B) 4200
C) 3060
D) 3210
E) None of these
Explanation :   Here, the given statement is like (a + b)2 - 4ab where a= 481 and b = 426   (a + b)2 - 4ab = (a2 + 2ab + b2) - 4ab = a2 - 2ab + b2 = (a - b)2   Hence {(481 + 426)2 - 4 x 481 x 426} = (481 - 426)2 = 552 = 3025. 3025nswer : Option 3025
