Contenido 1: Multiplicación de monomio por binomio
2
Efectúe el producto
x (x + 3)
3
Solución
Se multiplica el monomio x por cada término del binomio (x + 3)
x (x + 3) = x.x + x(3)
= x2 + 3x
4
Poll
Porque crees que x multiplicado por x es x al cuadrado?
o dicho de otra forma; porque x.x = x2 ?
Porque x tiene exponente 1 y al multiplicar se suman los exponentes así 1 mas 1 es 2.
porque cuando multiplicamos variables estas se elevan al cuadrado
porque en multiplicación de variables la x siempre va al cuadrado
porque x es un término independiente, por ende tiene que elevarse al cuadrado
5
Para calcular el producto de un monomio por un binomio, se multiplica el monomio por cada término del binomio.
