simplify (x−1−i)(x+1−i)

Solution

(x²−2)−2xi

Solution steps

One step at a time

(x−1−i)(x+1−i)

Rewrite x−1−i in standard complex form: (x−1)−i

Rewrite x+1−i in standard complex form: (x+1)−i

=((x−1)−i)((x+1)−i)

Apply complex arithmetic rule: (a+bi)(c+di)=(ac−bd)+(ad+bc)i

=((x−1)(x+1)−(−1)(−1))+((x−1)(−1)−1· (x+1))i

Simplify ((x−1)(x+1)−(−1)(−1))+((x−1)(−1)−1· (x+1))i: (x²−2)−2xi

=(x²−2)−2xi

Solve instead

ddx ((x−1−i)(x+1−i))
