7. ¿Cuál es el resultado de la siguiente suma de polinomios [tex]7x^4 + 4x^2 + 7x + 2[/tex] y [tex]6x^3 + 8x + 3[/tex]?

Sagot :

Para resolver la suma de los polinomios dados, vamos a sumar los coeficientes correspondientes de cada término. Los polinomios que tenemos son:

1. \(4x^2 + 7x + 2\)
2. \(6x^3 + 8x + 3\)

Primero, escribamos los polinomios de manera alineada según sus grados:

[tex]\[ \begin{array}{rcl} & 0x^3 + 4x^2 + 7x + 2 \\ + & 6x^3 + 0x^2 + 8x + 3 \\ \end{array} \][/tex]

Ahora, sumemos los coeficientes de cada término.

[tex]\[ \begin{array}{rcl} 0x^3 + 6x^3 & = & 6x^3 \\ 4x^2 + 0x^2 & = & 4x^2 \\ 7x + 8x & = & 15x \\ 2 + 3 & = & 5 \\ \end{array} \][/tex]

Entonces, la suma de los polinomios es:

[tex]\[ 6x^3 + 4x^2 + 15x + 5 \][/tex]

Por lo tanto, el resultado de sumar los polinomios \(4x^2 + 7x + 2\) y \(6x^3 + 8x + 3\) es:

[tex]\[ 6x^3 + 4x^2 + 15x + 5 \][/tex]
