Question

resolver los siguientes productos notables 1.(8x*2-11y*3)(8x*2+11y*3) 2.(9m*4-mn*2)(9m*4+mn*2)

Answer 1

Respuesta:

Explicación paso a paso:

1.(8x*2-11y*3)(8x*2+11y*3)

=(8x(2)+−33y)(8x(2)+11y(3))

=(8x(2))(8x(2))+(8x(2))(11y(3))+(−33y)(8x(2))+(−33y)(11y(3))

=256x2+528xy−528xy−1089y2

=256x²−1089y²

2.(9m*4-mn*2)(9m*4+mn*2)

=(9m(4)+−2mn)(9m(4)+mn(2))

=(9m(4))(9m(4))+(9m(4))(mn(2))+(−2mn)(9m(4))+(−2mn)(mn(2))

=1296m²+72m²n−72m²n−4m²n²

=−4m²n²+1296m²

Suerte cariño!
