jika P(X) = X(X^3+3x^2+2) ,nilai P(-1)

[tex]p( - 1) = ( - 1)( { - 1}^{3}+ 3( { - 1}^{2}) + 2)[/tex]
[tex]p( - 1) = ( - 1)( - 1 + 3 + 2)[/tex]
[tex]p( - 1) = ( - 1)(4)[/tex]
[tex]p( - 1) = - 4[/tex]

p(x) = x(x^3 + 3x^2 +2)
p(-1) = ?

(Masukkan -1 ke dalam fungsi)
p(-1) = -1((-1)^3 + 3(-1)^2 + 2
p(-1) = -1(1 + 3 + 2)
p(-1) = -1 . 6

p(-1) = -6
