Разложите на множители а)3x^4-3y^4 б) 16a^8-16b^8

3(x²-y²)(x²+y²)=3(x-y)(x+y)(x²+y²²)
16(a^4-b^4(a^4+b^4)=16(a²-b²)(a²+b²)(a^4+b^4)=
=16(a-b)(a+b)(a²+b²)(a^4+b^4)

A) 3xˇ4-3y4 = 3(xˇ4-yˇ4)=3.(xˇ2+yˇ2)(xˇ2-yˇ2)=3.(xˇ2+yˇ2)(x+y)(x-y)
b)16aˇ8-16bˇ8=16( aˇ8-bˇ8)=16.(aˇ4+bˇ4)(aˇ4-bˇ4)=
=16.(aˇ4+bˇ4)(aˇ2+bˇ2)(a+b)(a-b)
