contoh soal

P\left(x\right)=2x^3-4x+5\ dan\ Q\left(x\right)=-5x^3+2x^2-4x-10.

hitunglah hasil dari P(x) + Q(x) =

4

P(x) + Q(x) = ...

$\left(2x^3-4x+5\right)+\left(-5x^3+2x^2-4x-10\right)$
$2x^3-5x^3+2x^2-4x-4x+5-10$
$-3x^3+2x^2-8x-5$

kerjakan soal di bawah ini!

$f\left(x\right)=x+1$
$g\left(x\right)=x^2-2x+1$
$h\left(x\right)=x^3+6x^2+11x+6$
$a.\ f\left(x\right)+g\left(x\right)=...$
$b.\ f\left(x\right)+h\left(x\right)=...$
$c.\ g\left(x\right)+h\left(x\right)=...$
