Answer:

A = 0

B = -2/3

Step-by-step explanation:

√7-1                √7+1

______  -      _______   =   a+b√7

√7+1               √7-1  

√7-1     *√7-1                 √7+1    * √7+1  

_____    _____     -        _____    _____     =   a+b√7

√7+1        √7-1                 √7-1        √7+1

(√7-1)²              (√7+1)²

______    -       _______  =  a+b√5 7

√7² - 1               √7²-1

7+1-2√7              7+1+2√7

______      -       ________ = a+b√7

7-1                          7-1

8-2√7            8+2√7

______  -      ______  = a+b√7

6                       6

8-2√7 - 8-2√7

-------------------     =    a+b√7

6

-4√7/6  = a+b√7

-2√7/3 = a+b√7

a = 0/3

b = -2/3
