D) On transforme pour mettre en une équation
0.3x²+2x-5+1=0
0.3x²+2x-4 =0 est de la forme ax² +bx+c=0 avec a=0.3, b=2 et c=-4
Puis on calcul le discriminant DELTA :
D = b²-4ac
D = 2²-4*0.3*(-4)
D = 4+4.8
D = 8.8
D > 0 le trinome admet deux racines distinctes
X1 = -b-racine de D / 2a
X1 = -2-racine de 8.8 /0.6
X1 = -8.2774656580638
X2 = -b+racine de D /2a
X2 = -2+racine de 8.8 /0.6
X2 = 1.6107989913971
Donc 0.3x²+2x-4=0 quand x=-8.2774656580638 et x=1.6107989913971
