Answer:

you have studied algebraic expressions their addition,subtraction, multiplication and division in earlier classes.You also have studied how to factorise some algebraic expressions you may recall the algebraic expressions identities.

Step-by-step explanation:

1. (x+y) square = X square + 2 X Y + Y square

2.( x- y ) square = x square - 2 X Y + Y square

3. x square-y square =( x + y)( x - y )

4.( x+ a) (x + b) = x square +( a + b )x + ab

5.(x+y)cube= x cube + y cube + 3 x y( x + Y )

6.( x - y )cube = x cube -3 x square y + 3 x y square - y cube
