Question

(12x 3 – 7y 5 )(3x 3 -8y 5 )=


(16z 6 -7y 5 )(-12z 6 +22y 5 =

quien me ayuda es binomios y no le entiendo

Answer 1

(12x(3)−7y(5))(3x(3)−8y(5))

=(12x(3)+−35y)(3x(3)+−40y)

=(12x(3))(3x(3))+(12x(3))(−40y)+(−35y)(3x(3))+(−35y)(−40y)

$=324x^{2} -1440xy-315xy+1400y^{2}$

$\boxed{=324x^{2}- 1755xy+1400y^{2}}$
