Question

verify that a a-b not equal to b-a and the question is a=-3/5,b=-2/7​

Answer 1

a- b

$- \frac{3}{5} - ( - \frac{2}{7} ) \\ - \frac{3}{5} + \frac{2}{7} = \frac{ - (3 \times 7) + (5 \times 2)}{(5 \times 7)} = - \frac{ - 21 + 10}{35} = \frac{-11}{35}$

b - a

$- \frac{2}{7} - ( - \frac{3}{5} ) \\ - \frac{2}{7} + \frac{3}{5} = \frac{ - (2 \times 5) + (7 \times 3)}{(7 \times 5)} = \frac{ - 10 + 21}{35} = \frac{11}{35}$

So, we can see that a - b (-11/35) is not equal to b - a (11/35).

LHS is not equal to RHS

Hence verified.
