If x cannot equal 2, the 3x^2(x-2) - x +2 / x-2 = A. 3x^2 - x + 2 B. 3x^2 + 1 C. 3x^2 D. 3x^2 - 1 E 3x^2 - 2 Answer is [spoiler] D [/spoiler] As simple as that... Take (x-2) common in the numerator. You will be left with, (3x^2 - 1) Therefore, [(3x^2 - 1)(x-2)] /(x-2) = (3x^2 - 1). Hope this helps....

Then h(100) + 1 = 2^(50)*(1*2*3 ... *50) + 1 Now, h(100) + 1 cannot have any prime factors less than 50, because dividing this value by any of these prime numbers will give a remainder of 1. The correct answer is E. Hi Anju, I couldn't understand the above statement, i.e., Now, h(100) + 1 cannot ha...
