Question

P (x) = x al cuadrado - 2x + 2, calcula P (2)+ P(3)

Answer 1

Hola!!☺☺

Para hallar P(2) reemplazaremos x = 2

$P(x) = {x}^{2} - 2x + 2 \\ \\ x = 2 \\ \\ P(2) = {2}^{2} - 2(2) + 2 \\ \\ P(2) = 4 - 4 + 2 \\ \\ P(2) = 2$

Para hallar P(3) reemplazaremos x = 3

$P(x) = {x}^{2} - 2x + 2 \\ \\ x = 3 \\ \\ P(3) = {3}^{2} - 2(3) + 2 \\ \\ P(3) = 9 - 6 + 2 \\ \\ P(3) = 5$

Ahora P(2) + P(3) = 2 + 5 = 7
