Question

plz give the answer with full step...firstly solve in ur book then send​

Answer 1

Given: (41c+22b)-(12a-8b+17)+(8a²-4a³+2b-1)

To find: solution after the following mathematical operation

Solution: First we take the expressions 41c+22b and 12a-8b+17.

We are asked to substract 12a-8b+17 from 41c+22b. So,

                   41c+22b

                 -(12a-8b+17)    

                41c-12a+(22+8)b -17   (∵ a,b,c are three separate variables)

           = 41c-12a+30b -17  

Now we are to add  this expression obtained to  8a²-4a³+2b-1 as given in the question. So,

          41c-12a+30b -17

        +(8a²-4a³+2b-1)                      

         41c-12a+(30+2)b -(17+1)+8a²-4a³

      = 41c-12a+32b -18+8a²-4a³

which is the final answer after solving the expressions

ANS: 41c-12a+32b -18+8a²-4a³
