Question

add the following monomials 3a,4b,-6a_2b,_5a,10b

Answer 1

3a+4b-6a-2b-5a+10b

=3a-6a-5a+4b-2b+10b

=-3a-5a+14b-2b

=-8a+12b

is this answer right when the underscores are taken as negative sign

Answer 2

$\boxed{\boxed{\boxed{\bold{\purple{solution : \longrightarrow}}}}}$

$\bold{= 3a + 4b + ( - 6a) - 2b + ( - 5a) + 10b} \\ \\ \bold{= 3a + 4b - 6a - 2b - 5a + 10b} \\ \\ = \bold{3a - 6a - 5a + 4b - 2b + 10b} \\ \\ = \bold{- 8a + 12b}$
