Question

P(n)=5n2 + 3(n) + 8 Calcular: P(-3) + P(3)

Answer 1

$p( - 3) = 5 \times ( - 3)^{2} + 3 \times ( - 3) + 8$

$p( - 3) = 5 \times 9 - 9 + 8$

$p( - 3) = 45 - 9 + 8$

$p( - 3) = 44$

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

$p(3) = 5 \times {(3)}^{2} + 3 \times 3 + 8$

$p(3) = 5 \times 9 + 9 + 8$

$p(3) = 45 + 9 + 8$

$p(3) = 62$

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

$p( - 3) + p(3) = 44 + 62 = 106$

espero haberte ayudado.
