Explicación paso a paso:
*X² + 5X + 6 = 0 * X² + 7X + 12 = 0 * X² + 2X + 1 = 0
(x+2)(x+3) = 0 (x+3)(x+4)=0 (x+1)(x+1)=0
x+2=0 , x+3=0 x+3=0 , x+4=0 x+1=0 , x+1=0
x=−2 , x=−3 x=−3 , x=−4 x=−1
*X² + 4X + 4 = 0 * X² + 6X + 8 = 0 *X² + 11X + 10 = 0
(x+2)(x+2)=0 (x+2)(x+4)=0 (x+1)(x+10)=0
x+2=0 , x+2=0 x+2=0 , x+4=0 x+1=0 , x+10=0
x=−2 x=−2 , x=−4 x=−1 , x=−10
