Question

(x+4) (x-y)= x2-y2 identity and property​

Answer 1

Answer:

A= x 2−y 2 )(x−y)(x+y)

(x 2 +y 2 )(x 4 +y 4 ) { Using property (x+y)(x−y)=x

2 −y 2 }A=(x 2 −y 2 )(x 2 +y 2 )(x 4 +y 4 )=(x 4 −y 4)(x 4 +y 4 ) → Using the same property

A=(x 4 −y 4 )(x 4 +y 4 )=(x 8 −y 8 ) → Using the same property
