Question

Please tell me how we can use brackets in algebra?

Answer 1

if a sum is there - 6x+3y+2x+7y

then it can be written as x(6+2) + y(3+7)

Answer 2

while removing brackets we must first do the operations inside the bracket then the outside one
for example...
12[5+2-3]
12[8-3]
12[5]
60
brackets are nothing but a matter of simplification....
21[5+6-2]is a simplified form than..
105 + 126 - 42 this one is not a simplified form
I THINK THIS WILL HELP U
USING BRACKETS IS VERY SIMPLE.
IF U FEEL ITS HELFULL PLEASE MARK AS BEST...
