Question

Resultado de x2 +5x+4=0

Answer 1

Respuesta:

-4

Explicación paso a paso:

X2+ 5 x + 4 = 0

( 1 ) ⋅X2+ ( 5 ) ⋅ x + ( 4 ) = 0

x =- ( 5 ) ±( 5 )2- 4 ⋅ ( 4 )----------√2

x =- 5 ±25 - ( 16 )--------√2

x =- 5 ±9-√2

x =- 5 ± ( 3 )2

X1=- 22=( 2 )⋅ ( - 1 )( 2 )= - 1

X2=- 82=( 2 )⋅ ( - 4 )( 2 )= - 4
