Answer 2

Hola ;D

2x( x + 2 ) - 3( 5 - x ) = x + 5( x - 3 )

2x^2 + 4x - 15 + 3x = x + 5x - 15

2x^2 + x = 0

Por formula general

x = ( -1 +- √( 1^2 - 4( 2 ) ( 0 ) ) ) / ( 2 ( 2 ) )

x = ( -1 +- √1 ) / 4
______________

x1= ( -1 - 1 ) / 4

x1 = -2/4

x1 = -1/2
_________

x2 = ( -1 + 1 ) / 4

x2 = 0/4

x2 = 0
_________

RPTA: Los valores de "x" son -1/2 y 0
___________
