question 71

Multiple Choice

Which of the following equations is not an identity equation?

• A) \(- 2 + \frac { 1 } { x + 1 } = \frac { - 2 x - 1 } { x + 1 }\)
• B) \(- 2 ( x + 1 ) = - 2 x + 1\)
• C) \(- ( - 2 - x ) = x + 2\)
• D) \(\frac { 2 } { x } + \frac { 1 } { x } = \frac { 3 x } { x ^ { 2 } }\)
• E) \(x ^ { 2 } - 2 ( x + 2 ) = x ^ { 2 } - 2 x - 4\)
