lesya692 [45]

Answer:

El resultado eres: R(x) + S(x) = -6x^2 - 2x - 2

Step-by-step explanation:

Se dan las siguientes funciones

R(x) = -5x^2 + x - 2

S(x) = -x^2 - 3x

Cuál es el resultado de R(x) + S(x) ?​

Se soman los fatores en comun. Entonces:

R(x) + S(x) = -5x^2 + x - 2 + (-x^2 - 3x) = -5x^2 + x - 2 - x^2 - 3x = -5x^2 - x^2 + x - 3x - 2 = -6x^2 - 2x - 2

El resultado eres: R(x) + S(x) = -6x^2 - 2x - 2
