x²+5x+6 = 0 a = 1, b = 5, c = 6 Delta = b² - 4ac = 25 - 4*1*6 = 25 - 24 = 1 x1,2 = (-b +/- √delta)/2a x1 = (-5+1)/2 = -4/2 = -2 x2 = (-5-1)/2 = -6/2 = -3

x²+5x+6=0

x²+3x+2=0

x•(x+3)+2x+6=0

x•(x+3)+2(x+3)=0

(x+3)•(x+2)=0

x+3=0=>x=-3

x+2=0=>x=-2

[tex] = > x_{1} = - 3 \\ \\ \: \: \: \: \: \: \: \: x_{2} = - 2 [/tex]
