Multiplicación de Binomios con un Término Común

 (x+a)(x+b)=x2+(a+b)+(a)(b)\left(x+a\right)\left(x+b\right)=x^2+\left(a+b\right)+\left(a\right)\left(b\right)  

 (x+a)(xa)=x2a2\left(x+a\right)\left(x-a\right)=x^2-a^2  

 (x±a)2 =x2±2xa+a2\left(x\pm a\right)^2\ =x^2\pm2xa+a^2  

 (x±a)3=x3 ±3x2a+3xa2±a3\left(x\pm a\right)^3=x^3\ \pm3x^2a+3xa^2\pm a^3
