(x^2 + 2x - 8)/(x^2 - 6x + 8) = ? GMAT Problem Solving

Question:

\(\frac{x^2+2x-8}{x^2-6x+8} = ?\)

1. 1
2. -1
3. \(\frac{1}{3}x\)
4. \(\frac{x+4}{x-4}\)
5. \(\frac{x+8}{x-8}\)

Correct Answer: (D)

Approach Solution 1 :

Let us solve the equation by simplifying and evaluating.

=> [(x^2) + 2x - 8)] / [(x^2) - 6x + 8)] = [(x - 2)(x + 4)] / [(x - 2)(x - 4) ]
= (x + 4)/(x - 4)
