Answer :
A B C
× A A
----------------------------
A² AB AC
A² AB AC
----------------------------------------------
A² A(A+B) A(B+C) AC
A² = A A(A+B) = C A(B+C) = 6 AC = C
from AC = C A = 1
1+B = C & B + C = 6
2B = 5
B = 5/2
C = 7/2
× A A
----------------------------
A² AB AC
A² AB AC
----------------------------------------------
A² A(A+B) A(B+C) AC
A² = A A(A+B) = C A(B+C) = 6 AC = C
from AC = C A = 1
1+B = C & B + C = 6
2B = 5
B = 5/2
C = 7/2
