# Q11 (2,6) ÷ (3,7)

(2,6) ÷ (3,7)

SOLUTION:

= (2,6) ÷ (3,7)

=
 (2,6) (3,7)

=
 (2,6) (3,7)
x
 (3,-7) (3,-7)

=
 (2,6)(3,-7) (3,7)(3,-7)

=
 [(2)(3)-(6)(-7),(2)(-7)+(6)(3)] [(3)(3)-(7)(-7),(3)(-7)+(7)(3)]

=
 (6+42,-14+18) (9+49,-21+21)

=
 ( 48 , 4 ) ( 58 , 0 )

=
 ( 48 , 4 ) 58
∴ (58,0)=58

= (
 48 58
,
 4 58
)

= (
 24 29
,
 2 29
)
