Question

ayuda urgente porfavor se los suplico ecuaciones cuadraticas por FORMULA GENERAL

Answer 1

3x²-5x+2 = 0
x = {5+-√(-5² -(4*3*2))}/2*3
x = {5+-√(25-24)} / 6
x = {5+-√1} / 6
x = {5+-1}/6

x₁ = (5-1)/6 = 4/6 = 2/3
x₂ = (5+1)/6 = 6/6 = 1



x²-16x+63 = 0
x = {16+-√(-16²-4*(1*63))}/2*1
x = {16+-√(256-252)}/2
x = {16+-√4}/2
x = {16+-2} / 2

x₁ = {16-2}/2 = 14/2 = 7
x₂ = {16+2}/2 = 18/2 = 9
