Question

cuanto es ? (x+3)×(x+2)= 12 es para mañana​

Answer 1

Explicación paso a paso:

$(x+3)×(x+2)= 12$

${x}^{2} + 2x + 3x + 6 = 12$

${x}^{2} + 5x + 6 = 12$

${x}^{2} + 5x + 6 - 12 = 0$

${x}^{2} + 5x - 6 = 0$

$(x + 6)(x - 1) = 0$

____________________________________$x + 6 = 0$

$x1 = - 6$

____________________________________$x - 1 = 0$

$x 2= 1$

Answer 2

Respuesta:

(x2+5x+6)−{12}=0

x2+5x−6=0

(1)⋅x2+(5)⋅x+(−6)=0

x=−(5)±(5)2−4⋅(−6)−−−−−−−−−−−−√2

x=−5±25−(−24)−−−−−−−−−−√2

x=−5±49−−√2

x=−5±(7)2

x1=22=(2)(2)=1

x2=−122=(2)⋅(−6)(2)=−6
