Question

Subtraindo os dois polinômios P(x) = x³ + 4x² + 2x + 1 e Q(x) = x³ + 4x² temos:

A)P(x) - Q(x) = 2x³ + 8x²
B)P(x) - Q(x) = 2x³ + 2x + 1
C)P(x) - Q(x) = 2x + 1
D)P(x) + Q(x) = 2x³ + 1

Answer 1

$\mathsf{x^{3}+4x^{2}+2x+1-x^{3}-4x^{2}=2x+1}$

$\boxed{\boxed{\boxed{\mathsf{P(x)-Q(x)=2x+1}}}}$
