Aplicar FOIL paso a paso
La calculadora multiplicará dos binomios utilizando el método FOIL, y se muestran los pasos.
Tu aportación
Multiplica $$$\left(2 x + 1\right) \left(5 x + 7\right)$$$ usando FOIL.
Solución
$$$\left({\color{red}\left(2 x\right)} + {\color{purple}\left(1\right)}\right) \left({\color{green}\left(5 x\right)} + {\color{blue}\left(7\right)}\right) = \underbrace{{\color{red}\left(2 x\right)} {\color{green}\left(5 x\right)}}_{\text{Primero}} + \underbrace{{\color{red}\left(2 x\right)} {\color{blue}\left(7\right)}}_{\text{Exterior}} + \underbrace{{\color{purple}\left(1\right)} {\color{green}\left(5 x\right)}}_{\text{Interno}} + \underbrace{{\color{purple}\left(1\right)} {\color{blue}\left(7\right)}}_{\text{Último}} = 10 x^{2} + 14 x + 5 x + 7 = 10 x^{2} + 19 x + 7$$$
Respuesta
$$$\left(2 x + 1\right) \left(5 x + 7\right) = 10 x^{2} + 19 x + 7$$$A
