Question

lesson 9 .Algebraic expression and identities
excrise 9.5 4th main i) ( a²-b²)²

please guys i need very early answer ​

Answer 1

Answer:

(a^2-b^2)^2

= (a^2)^2 + (b^2)^2 - 2(a^2)(b^2)

=a^4 + b^4 - 2a^2b^2

Step-by-step explanation:

In Algebraic Identity ll we have the formula for simplifying (a-b)^2 which is equal to a^2+b^2-2ab . So here we have a = a^2 and b=b^2 . Using this Algebraic Identity ll , we can solve this question by this method .

Hope it helps you
