<br />
On calcule séparément en remplaçant x par 2 dans chaque membre:<br />
1er membre: 5 x 2 - 1 = 9<br />
2nd membre: -3 x 2 + 15 = 9<br />
les résultats sont les mêmes donc 2 est bien la solution<br />

on remplace x par -2 dans le 1er membre, on obtient alors:</div>
<div>
5 x (-2)² - 4 x (-2) = 5 x 4 + 8 = 28 on tombe sur le 2nd membre donc -2 est la solution</div>

<b><br /></b>
<b>QUOI?</b><br />
<b><br /></b>
<b>Droite ( ou segment)</b><br />
<b>Passant par <span style="color: red;">un sommet</span></b><br />
<b>et <span style="color: red;">perpendiculaire </span></b><br />
<b>au côté <span style="color: red;">opposé</span></b><br />
<b><span style="color: red;">-dans le cas du triangle ABC ayant un angle </span><span style="color: blue;">obtus</span><span style="color: red;"> on obtient une hauteur à </span><span style="color: blue;">l'extérieur </span><span style="color: red;">du triangle, cas du triangle "enrhumé" qui a la "goutte au nez")</span></b><br />
<b><span style="color: red;">- pour le triangle ABC ayant trois angles aigus, la hauteur représentée est</span><span style="color: blue;"> issue de C</span><span style="color: red;"> on dit aussi que la hauteur est </span><span style="color: blue;">relative au côté [BC]</span></b><br />
<b><span style="color: blue;"><br /></span></b>
<b>COMMENT?</b><br />
<b><br /></b>
<b>Avec une <span style="color: red;">équerre ou une réquerre </span></b><br />

<b>Dans "C'est quoi":</b><br />
<b><br /></b>
Seulement deux diviseurs: 1 et le nombre lui-même, exemples: 2; 3; 5; 7; 11; ....29........301<br />
Attention 1 n'est pas premier (c'est pour cela que sur l'image du podium 1 est barré)<br />
<br />
<br />
Un nombre est diviseur d'un autre lorsque le reste vaut 0 dans la division euclidienne.<br />
Par exemple 7 est un diviseur de 182<br />
<br />
<b>Dans "Pour quoi faire?":</b><br />
<br />
Les nombres premiers sont présents dans la nature: La cigale "Magicicada" ne sort de terre que tous les 13 ou 17 ans pour éviter de croiser des prédateurs dont le cycle de vie est pair<br />
Les engrenages comportent souvent un nombre premier de dents pour éviter qu'une dent ayant un défaut sur un des engrenages ne provoque une usure rapide de l'autre engrenage en "tombant" toujours sur la même dent<br />
Les nombres premiers sont présent dans les cryptages, voir le codage RSA (vidéo: <a href="https://www.youtube.com/watch?v=8BM9LPDjOw0">https://www.youtube.com/watch?v=8BM9LPDjOw0</a>)<br />
<br />
<b>Dans "Décomposer":</b><br />
<br />
Tous les nombres peuvent s'écrire sous la forme d'un produit de facteurs premiers<br />
<br />
<b>Dans "Fractions irréductibles":</b><br />
<br />
C'est lorsque le numérateur et le dénominateur n'ont aucun diviseur commun sauf le chiffre 1<br />
<br />

<b>Dans C'EST QUOI?</b><br />
<br />
Ce sont des mouvements que l'on fait faire à une figure de départ, la figure obtenue s'appelle l'image<br />
<br />
<b>Dans POURQUOI?</b><br />
les transformations sont utiles en architecture, pour l'esthétique, pour fabriquer des objets,...<br />
<br />
<b>Dans SYMÉTRIES:</b><br />
- Axiale: par rapport à une <b>droite</b>, c'est faire un <b>pliage <a href="http://mep-outils.sesamath.net/manuel_numerique/diapo.php?atome=60827&ordre=2">détails de constructions</a></b><br />
- Centrale: par rapport à un <b>point</b>, on fait un <b>demi-tour <a href="http://mep-outils.sesamath.net/manuel_numerique/diapo.php?atome=77521&ordre=1"> détails de construction</a></b><br />
<br />
<b>Dans ROTATIONS:</b><br />
C'est lorsque l'on fait <b>tourner </b>une figure<br />
Autour d'un <b>point</b><br />
Dans un <b>sens </b>donné (direct ou indirect): ici la flèche bleue du dessin indique le sens indirect, sens des aiguilles d'une montre<br />
Avec un <b>angle </b>donné<br />
<a href="http://mep-outils.sesamath.net/manuel_numerique/diapo.php?atome=77528&ordre=1"><b>détails de constructions</b></a><br />
<br />
<b>Pont entre rotations et symétries centrales: </b>C'est lorsque l'angle de la rotation<b> vaut 180° </b><br />
<br />
<b>Dans TRANSLATIONS:</b><br />
C'est lorsque l'on fait <b>glisser </b>une figure<br />
Dans une <b>direction </b>donnée<br />
Dans un <b>sens </b>donné<br />
Avec une <b>longueur </b>donnée<br />
à côté des petits bateaux: On obtient des <b>parallélogrammes </b><br />
