4t ESO/4.03 POLINOMIS/4.03.2 Polinomis: Operacions 4.03.2.10 TEORIA: ADDICIÓ DE POLINOMIS

Addició de polinomis

Per a sumar polinomis, sumem els monomis de mateix grau.

Exemple:
(-2x⁴ + 7x³+ 6x² + 3x - 1) + (4x³- 6x² + 9x - 5) =

-2x⁴ + 11x³ + 12x - 6

Perquè:
-2x⁴ + 0 = -2x⁴7x³+ 4x³= 11x³6x²+ (- 6x²) = 0x²(que no s'escriu)
3x + 9x = 12x
- 1+(-5) = -6

Exemple:
(-2x⁴ + 7x³+ 6x² + 3x - 1) - (-5x⁴- 6x² + 3x - 5) =

3x⁴ + 7x³+ 12x²+ 4

Perquè:

3x - 3x = 0x (que no s'escriu)

]]> 4.03.2.30 TEORIA: MULTIPLICAR MONOMI PER POLINOMI

Multiplicació d'un monomi
per un polinomi

Per a multiplicar el polinomi P(x) per un monomi, multipliquem tots els monomis de P(x) per aquest monomi.

Exemple:
(-2x⁴)·(7x³- 6x² + 3x - 1) = -14x⁷+ 12x⁶ - 6x⁵+ 2x⁴

Perquè:
(-2x⁴)· 7x³ =-14x⁷(-2x⁴)·(-6x²) = 12x⁶
(-2x⁴)·3x = -6x⁵
(-2x⁴)·(- 1) = 2x⁴

]]> 4.03.2.40 TEORIA: MULTIPLICACIÓ DE POLINOMIS

Multiplicació de 2 polinomis

Per a multiplicar el polinomi P(x) pel polinomi Q(x) multipliquem TOTS els monomis de P(x) per TOTS els monomis de Q(x). Agrupem i ordenem.

Exemple:
(-2x²+3x)·(7x³+ 2x - 1)
= (-2x²)· 7x³ + (-2x²)·2x + (-2x²)·(-1) + 3x·7x³ + 3x·2x + 3x·(- 1)
= -14x⁵- 4x³+ 2x²+ 21x³+ 6x²- 3x

Agrupat i ordenat: -14x⁵ + 17x³ + 8x²- 3x
