Resuelve la ecuación 3x² + 5x = 2?
Resuelve la ecuación 3x² + 5x = 2.
Resuelve la ecuación 3x² + 5x = 2.
ax² + bx + c = 0
En resumen
3x² + 5x - 2 = 0 x = [ - 5 + - √(5² - 4(3 * - 2))] / 2 * 3 x = [ - 5 + - √(25 + 24)] / 6 x = [ - 5 + - √49] / 6 x = [ - 5 + - 7] / 6 x₁ = [ - 5 - 7] / 6 = - 12 / 6 = - 2 x₂ = [ - 5 + 7] / 6 = 2 / 6 = 1 / 3.
3x² + 5x - 2 = 0
x = [ - 5 + - √(5² - 4(3 * - 2))] / 2 * 3
x = [ - 5 + - √(25 + 24)] / 6
x = [ - 5 + - √49] / 6
x = [ - 5 + - 7] / 6
x₁ = [ - 5 - 7] / 6 = - 12 / 6 = - 2
x₂ = [ - 5 + 7] / 6 = 2 / 6 = 1 / 3.
4x + 3 = 2x + 9 4x - 2x = - 3 + 9 2x = 3 ___________________________________________________________ (5x / 2) + 2 = 20 + 2 (5x / 2) = 20 + 2 - 2 5x = 2(20) x = 40 / 5 x = 8…
Te voy a dar un ejemplo para que te sea mas facil : x + 2 : 4 x : 2 - 4 x : 2.
