12. Si R(x)=-5x2+x-2 y S(x)=-x - 3x, se<br>¿cuál es el resultado de R(x) + S(x) ?

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: $R(x) + S(x) = -6x^2 - 2x - 2$
