Question

find the value of a and b is 7 + 3 root 5 by 3 + root 5 minus 7 minus 3 root 5 by 3 minus root 5 is equal to a + root 5 b

Answer 1

7+ root 5 by 3 - root 5 - 7 - 3 root 5 by 3 - root 5 = a + root 5b

0 = a + root 5b. ...........1

a = - root 5

- ( root 5b ) = a

- 5b = a square

b = -a square by 5

Value of a is given as

Put the value of b in equation 1

0 = a + root 5 - a square by 5

a. = - ( Root 5 - a square by 5 )
