How do you simplify the expression (x^2 - 4)/(x + 2)?
Answer 1
Edward Davis
To simplify the expression (x^2 – 4)/(x + 2), first recognize that x^2 – 4 is a difference of squares and can be factored into (x + 2)(x – 2). The expression then becomes [(x + 2)(x – 2)] / (x + 2). By cancelling the common factor (x + 2), the simplified expression is x – 2, for x ≠ -2.
