Question

hallar x : 6x² - 13x + 5 = 0

Answer 1

Respuesta:

C.S. = { 5/3 ; 1/2 }

Explicación paso a paso:

Recuerda :

• $a.b=0$ => $a=0$ ∨ $b=0$

-------------------------------------------------------------------------------------------------

Factorizamos :

$6x^{2} -13x+5=(3x-5)(2x-1)$

-------------------------------------------------------------------------------------------------

Entonces :

$6x^{2} -13x+5=0\\\\(3x-5)(2x-1)=0$  

-------------------------------------------------------------------------------------------------

Por propiedad (Está en "recuerda") :

$(3x-5)(2x-1)=0$

$3x-5=0\\\\3x=5\\\\x=5/3$    ∨   $2x-1=0\\\\2x=1\\\\x=1/2$

-------------------------------------------------------------------------------------------------

C.S. = { 5/3 ; 1/2 }
