Explicación paso a paso:
Calcular R !
Solución !
[tex](x + 7)(x + 5) - {(x + 6)}^{2} [/tex]
[tex] {x}^{2} + 5x + 7x + 35 - ( {x}^{2} + 2x \times 6 + {6}^{2} )[/tex]
[tex] {x}^{2} + 5x + 7x + 35 - {x}^{2} - 12x - 36[/tex]
[tex]( {x}^{2} - {x}^{2} ) + (5x + 7x - 12x) + (35 - 36)[/tex]
[tex]r = - 1[/tex]
