If a > 1, which of the following is equal to (2a - 2)/(a^2 + 2a - 3)?  Choices:  A) a  B) a + 3  C) 2/(a - 1)  D) 2/(a + 3)  E) (a - 1)/2
Here's the algebraic approach:   (2A - 2)/(A^2 + 2A - 3) can be rewritten as...   2(A - 1)/(A+3)(A-1)   We can simplify the fraction, which leaves us with...   2/(A+3)   Ans : 2/(a + 3)
