Answer 1

$\sf\huge\bold{\underline{\underline{{Solution}}}}$

How to solve :

step 1:first step is to solve the terms inside small brackets.

Step 2:After solving the terms inside small brackets solve it with the whole terms inside brackets and evaluate it.

Step 3: Multiply it with each and every term outside the bracket..

Step 4: Remove all brackets and solve it as a whole .

Step 5:Make like terms together and if the terms can factorise then factorise it or take common.

➝10-[4xy+3{x²-(xy-y)-(x-y+1)}]

First step is to solve the terms inside brackets

➝10-[4xy+3{x²-xy+y-x+y-1}]

➝10-[4xy+3{x²-xy+2y-x-1}]

➝10-[4xy +3x²-3xy+6y-3x-4]

➝10-[4xy-3xy+3x²+6y-3x-4]

➝10-[xy+3x²+6y-3x-4]

Remove the brackets and expanding the terms

➝10-xy-3x²-6y+3x+4

➝10+4-3x²-xy-6y+3x

➝-3x²-xy+3x-6y+14

➝3x²+3x-xy-6y+14

Taking 3x common from 3x² +3x

➝3x(x+1)-xy-6y +14

taking y common from -xy-6y

➝3x(x+1) -y(x+6)+14
