Answer 2

at first we have to open the bracket by multiplying the signs

then, we have to take L.C.M of 12 and 14 that is 84

then, we have to see in 12 table in how many times 84 comes and as we know that 12×7 = 84 then we have to multiply 7 with 5 as we know 7× 5 = 35 (-) sign will be copied down

Then again we have to see that in 14 table in how many time 84 comes we know that 14×6 = 84 then again we have to multiply 7×6 = 42 then again(-)sing will be copied

at last we will take minus as common and add 35 +42 = -77 / 84 ( ANSWER)
