Question

binomios al cuadrado (⅛-¾b)²​

Answer 1

Respuesta:

$\frac{1 - 12b + 36 {b}^{2} }{64}$

Explicación paso a paso:

Binomio se la forma

${(a - b)}^{2} = {a}^{2} - 2ab + {b}^{2}$

${( \frac{1}{8} - \frac{3b}{4} ) }^{2}$

${( \frac{1}{8}) }^{2} - 2( \frac{1}{8} )( \frac{3b}{4} ) + { (\frac{3b}{4} )}^{2}$

$\frac{1}{64} - \frac{3b}{16} + \frac{9 {b}^{2} }{16}$

$\frac{1 - 12b + 36 {b}^{2} }{64}$
