Question

(x+y)^2+2(x+y)(x-y)+(x-y)^2 ka factorisetion kaise hoga step by step solution​

Answer 1

Step-by-step explanation:

We know that

(a+b)² = a² + 2ab + b²

treat the (x+y) as a and (x-y) as b

so the above expression can be written as,

a² + 2ab + b²

= (a+b)²

= ((x+y) + (x-y))²

....cancel the +y and -y and add +x and +x

= (2x)²

= 4x²
