Question

-Calcule el valor de E para cada caso: a) P(x) = 5 2 (x + 2) (x - 3) Calcular: E = P (1) + P (4)

Answer 1

Respuesta:

Explicación paso a paso:

P(x) = 5/2 (x + 2) (x - 3)

E = P (1) + P (4)

P(1) = 5/2 (1 + 2) (1 - 3)

P(1) = 5/2× 3× (-2)

P(1) = 30/2 × (-2)

P(1) = 15×(-2)

P(1) = -30

P(4) = 5/2 (x + 2) (x - 3)

P(4) = 5/2 (4 + 2) (4 - 3)

P(4) = 5/2×6×1

P(4) = 17/2×1

P(4) = 19/2

E = P (1) + P (4)

E= -30 + $\frac{19}{2}$

E= $\frac{-30x2+19}{2}$

E= $\frac{-60+19}{2}$

E= $\frac{-41}{2}$
