forma general x²+7x+12=0 x²+8x+15=0 x²+5x+6=0 x²+14x+45=0 x²+4x+3=0 forma factorizada ( ) ( )=0
soluciones ​

Answer 1

Explicación paso a paso:

x²+7x+12=0

x +4 ( X + 4 )

x +3 ( x + 3 )

( x + 4 ) = 0 ( x + 3 ) = 0

x = - 4 X = -3

x²+8x+15=0

x +5 ( x + 5 )

x +3 (x + 3 )

(x + 5) = 0 ( x + 3) = 0

x = - 5 x = - 3

x²+5x+6=0

x + 6 ( x + 6 )

x - 1 ( x - 1 )

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

x = -6 x = 1

x²+4x+3=0

x +9 ( x + 9 )

x +5 (x + 5 )

(x + 9) = 0 ( x + 5) = 0

x = - 9 x = - 5
