Question

efectue (x+3sobre2)(x-3sobre2)

Answer 1

Efectue :

$\textbf{Aplicamos diferencia de cuadrados :} \\ \\ (a + b)(a - b)= x^{2} -y^{2} \\ \\ \\ }\left( \dfrac{x+3}{2} \right)\left( \dfrac{x-3}{2}\right) \\ \\ \\ \left( \dfrac{(x+3)(x-3)}{2*2} \right) \\ \\ \\ \dfrac{ x^{2}-9 }{4} \ \textless \ == Expresi\'on\ reducida.$

Si quieres la soluciones :

$\dfrac{ x^{2}-9 }{4} = 0 \\ \\ \\ x^{2}- 9 = 0 \\ \\ (x+3)(x - 3) = 0 \\ \\ x_{1}=-3 \ \ \ \ \ \ x_{2} = 3$
