Choisir la forme appropriée d'une fonction polynôme du second degré Problème

f\left(x\right)=9x^{2}-36x+20

f\left(x\right)=81x^{2}-36x

f\left(x\right)=81x^{2}-36x-12

f\left(x\right)=9x^{2}-36x-12

f\left(x\right)=\left(9x-6\right)\left(9x+2\right)

f\left(x\right)=\left(9x-2\right)\left(9x-32\right)

f\left(x\right)=\left(3x-6\right)\left(3x+2\right)

f\left(x\right)=\left(3x-10\right)\left(3x-2\right)
