Answer 1

Respuesta:

               1

Explicación paso a paso:

$M(x)= \frac{(x^{2}-x-12)(x^{2}-2x-63)(x^{2}-2x-35) }{(x^{2}-49)(x^{2} +x-20)(x^{2}-6x-27 ) }$

$M(x)= \frac{(x-4)(x+3).(x-9)(x+7).(x-7)(x+5)}{(x+7)(x-7).(x+5)(x-4).(x-9)(x+3)}$

$M(x) =\frac{(x-9)(x-7)(x-4)(x+3)(x+5)(x+7)}{(x-9)(x-7)(x-4)(x+3)(x+5)(x+7)}$

M( X ) =   1
