What did she do wrong

Answer 1

As seen on the picture, all the steps A to D are correct.

• Step A. Identity is correct
• Step B. The fraction is correct
• Step C. Simplification is correct
• Step D. Solution is correct

Note:

• It could be more simplified by adding a step and multiplying both the numerator and denominator by √3:

• 
  `(-√(2) )/(√(3) ) = - (√(6))/(3)`
