rewrite this number as a difference of two numbers. 
35=40-5
Show how to use the identity (x − y)2 = x2 − 2xy + y2 to square your number without using a calculator.
(35)^2=(40-5)^2=(40)^2-(5*2*40)+5^2
continue...

anonymous · Answer

So from on there that is right?

ikram002p · Answer

its right but u need to continue to find 30^2
(35)^2=(40-5)^2=(40)^2-(5*2*40)+5^2
                            =1600-400+25 =?
