Question

Escribir las ecuaciones de segundo grado a partir de sus soluciones (raíces) v X1 = 5 ; X2 = -6 v X1= 43 ; X2= -2

Answer 1

Respuesta:

Explicación paso a paso:

X1 = 5 ; X2 = -6

$x^{2} - ( x_{1} + x_{2} ) x+ (x_{1} * x_{2} )=0$

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

$x^{2} - ( -1 )x + ( -30)=0$

$x^{2} +x-30=0$

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

X1= 43 ; X2= -2

$x^{2} - ( x_{1} + x_{2} )x + (x_{1} * x_{2} )=0$

$x^{2} -(43+ (-2)) x + ( 43*-2)=0$

$x^{2} - ( 43-2 ) x + ( -86 ) =0$

$x^{2} -41x -86=0$
