GIVEN: x + 2 = (x + 11)/(x + 3)
Multiply both sides by (x+3) to get: (x + 3)(x + 2) = x + 11
Use FOIL to expand left side: x² + 5x + 6 = x + 11
Subtract x from both sides to get: x² + 4x + 6 = 11
Subtract 11 from both sides to get: x² + 4x - 5 = 0

QUESTION: What is the value of x² + 4x - 5?
Well, x² + 4x - 5 = 0

Answer: C

\(x + 2 = \frac{(x + 11)}{(x + 3)}\)

Or, \(x^2+5x+6 = x + 11\)

Or, \(x^2+ 4x = 5\)

So, \(x^2 + 4x - 5 = 0\), Answer must be (C)
