Question

Dado P(x)= 2x3y 6x2y y Q(x)=2xy calcule P(x)/Q(x) si x=3 : , .

Answer 1

Sea:

P(x)= 2x³y 6x²y

Q(x)=2xy

Para el valor de la variable x igual a 3 (X = 3), los polinomios quedan:

P (3) = 2(3)³y 6(3)²y

P (3) = 2(27)y 6(9)y =

P (3) = (54)y (54)y = 2.916y²

P (3) = 2.916y²

Q(3) = 2(3)y = 6y

Q(3) = 6y

P(3)/Q(3) = 2.916y2/6y = 486y

P(3)/Q(3) = 486y
