PRODUCTOS NOTABLES URGENTE! (x^2 - 1^2), (x+y)(x-y), (a-x)(x+a), (a^3+b^2)(a^3-b^2), (x+y+z)(x+y-z), (2a-b+c)

Answer 1

$x^{2} - 1^{2} = (x+1)(x-1)$

$(x+y)(x-y) = x^{2} - y^{2}$

$(a+x)(a-x) = a^{2} - x^{2}$

$(a^{3} + b^{2})( a^{3} - b^{2}) = a^{6} - b^{4}$

$(x+y+z)(x+y-z) = (x+y)^{2} - z^{2} = x^{2} +2xy + y^{2} - z^{2}$
