Question

Multiplicar: 1/2a-1/3b por 1/3a+1/2b​

Answer 1

Respuesta:

$(\frac{36a^{2} }{216} + \frac{30ab}{216} - \frac{ {36b}^{2} }{216} )$

Explicación:

(1/2a-1/3b)x(1/3a+1/2b)

(a/2-b/3)×(a/3+b/2)

$( \frac{ {a}^{2} }{6} + \frac{ab}{4} - \frac{ {ab}}{9} - \frac{ {b}^{2} }{6} )$

$(\frac{36a^{2} }{216} + \frac{54ab}{216} - \frac{24ab}{216} - \frac{ {36b}^{2} }{216} )$

$(\frac{36a^{2} }{216} + \frac{30ab}{216} - \frac{ {36b}^{2} }{216} )$
