Simplify x+2x+1 x + 2 x + 1 - x−2x+2
Answer Details
x+2x+1 x + 2 x + 1 - x−2x+2 x − 2 x + 2 = (x+2)(x+2)−(x−2)−(x−2)(x+1)(x+1)(x+2) ( x + 2 ) ( x + 2 ) − ( x − 2 ) − ( x − 2 ) ( x + 1 ) ( x + 1 ) ( x + 2 ) = (x2+4x+4)−(x2−x−2)(x+1)(x+2) ( x 2 + 4 x + 4 ) − ( x 2 − x − 2 ) ( x + 1 ) ( x + 2 ) = x2+4x+4−x2+x+2(x+1)(x+2) x 2 + 4 x + 4 − x 2 + x + 2 ( x + 1 ) ( x + 2 ) = 5x+6(x+1)(x+2)
