root7(root7-1)-1(root7-1)-root7(root7+1)+1(root7+1)/root7(root7-1)+1(root7-1)

7-root7-root7+1-7-root7+root7+1///7-root7+root7-1

Answer 2

Answer: a=  -√7    

b= -2/3

Step-by-step explanation

take L.H.S

1. [(√7 - 1) *(√7 - 1)]/[ (√7 + 1 ) * (√7 - 1) + [(√7 + 1 )*(√7 + 1 )] / [(√7 + 1 )* (√7-1)  ]
2. simplify this form and you will get
3. -√7 - (2√7)/3
4. compare L.H.S with R.H.S and get your answer
