2
Suma y resta de polinomios
Para sumar polinomios se suman o restan los términos semejantes; los términos no semejantes
se dejan como estaban.
3
Ejemplo suma:
a) (5x2−3x−6)+(3x3−2x2+5)=
=3x3+(5x2−2x2)−3x+(−6+5)=
=3x3+3x2−3x−1
4
Ejemplo resta:
b) (5x2−3x−6)−(3x3−2x2+5)=
=3x3+(5x2+2x2)−3x+(−6−5)=
=3x3+7x2−3x−11
5
Multiplicación de polinomios
Se multiplica cada término del primer polinomio por cada uno de los términos del segundo: “todos por todos”. Esto es, se aplica la propiedad distributiva del producto y las reglas de la potenciación. Una vez realizados los productos deben agruparse los términos semejantes.
6
Ejemplo:
(4x2−5x−6)•(2x2−3x)=
=(4x2•(2x2))+(4x2•(−3x))+(−5x•(2x2))+
+(−5x•(−3x))−(6•(2x2))−(6•(−3x))=
=8x4−12x3−10x3+15x2−12x2+18x=
=8x4−22x3+3x2+18x
7
Productos notables:
(a+b)2=a2+2ab+b2
(a−b)2=a2−2ab+b2
(a+b)∙(a−b)=a2−b2
8
Ejemplos:
a) (x2+3)2=x4+6x2+9
b) (4x−6)2=16x2−48x+36
c) (4x+3)•(4x−3)=(4x)2−32=16x2−9
