Question

Dado P(x)= x3+ 2x2+3x Q(x) = x3+ 2x2+x. calcule P(x)-Q(x) :

Seleccione una:
a. 4x
b. 2x
c. x
d. x3

Answer 1

P(x) = x³ + 2x² + 3x

Q(x) = x³ + 2x² + x

-------------------------

P(x) - Q(x) = x³ + 2x² + 3x - (x³+2x²+x)

P(x) - Q(x) = x³ + 2x² + 3x - x³ - 2x² - x

P(x) - Q(x) = 3x - x

P(x) - Q(x) = 2x
