Step-by-step explanation:

x^6 - y^6 = (x^2 + y^2)[ (x^2+y^2)^2 - (3x^2.y^2)]

= (x^2+y^2)(x^4 + y^4) - (x^2 . y^2)(x^2+y^2)

= (x^3+y^3)(x-y)(x^2+Y^2+xy)

Solution:

\longrightarrow\rm{x^6-y^6}

\longrightarrow\rm{(x^3)^2-(y^3)^2}

Now, we are going to use an identity: \rm{a^2-b^2 = (a+b)(a-b)} Let us use this identity:

\longrightarrow\rm{(x^3+y^3)(x^3-y^3)}

Further, we are going to use two more important identities:

  • \rm{(a^3+b^3) = (a+b)(a^2-ab+b^2)}
  • \rm{(a^3-b^3) = (a-b)(a^2+ab+b^2)}

Let us apply these two identities:

\longrightarrow\rm{(x^3+y^3)(x^3-y^3) = (x+y)(x^2-xy+y^2)(x-y)(x^2+xy+y^2)}

\longrightarrow\rm{(x+y)(x-y)(x^2-xy+y^2)(x^2+xy+y^2)}

Hence, your Question is factorized. From this, let us arrive the last statement for this problem:

\longrightarrow\rm{x^6-y^6 = (x+y)(x-y)(x^2-xy+y^2)(x^2+xy+y^2)}
