Question

2x²-x-6=0
resolverlo​

Answer 1

Respuesta:

2x² - x - 6 = 0

a = 2

b = - 1

c = - 6

x = [ - b ± √b² - 4ac]/2a

x = [ - ( - 1) ± √(- 1)² - 4(2)(-6)]/2*2

x = [ + 1 ± √1 + 48]/4

x = [1 ± √49)/4

x =[ 1± 7]/4

x1 = (1 + 7)/4

x1 = 8/4

x1 = 2

 o

x2 = (1 - 7)/4

x2 = - 6/4

x2 = - 3/2

Solucion.

( -3/2 , 2)
