Question

x2+5x-24=0 cual es valor de x

Answer 1

x +8
x -3
×2 + 8x - 3x -24 = 0
X2 + 5x - 24 = 0
Por ende
x + 8 = 0 y x - 3 = 0
x = -8 y x = 3

Answer 2

x²+5x-24 = 0
x = {-5+-√(5²-4(1*-24))} / 2*1
x = {-5+-√(25+96)} / 2
x = {-5+-√121}/2
x = {-5+-11}/2
x₁ = {-5-11}/2 = -16/2 = -8
x₂ = {-5+11}/2 = 6/2 = 3
Respuesta:
-8 y 3
