Question

La solucion de la ecuación: 5x2+ 7x+2=0

Answer 1

5X2=10+7=17X2=34 es facil :D

Answer 2

5x² + 7x + 2 = 0---por fórmula general

x₁ = - 7 + √((7)² - 4 * 5 * 2)/2 * 5

x₁ = - 7 + √(49 - 40)/10

x₁ = - 7 + √(9)/10

x₁ = (- 7 + 3)/10

x₁ = - 4/10

x₁ = - 2/5

x₂ =  (- 7 - 3)/10

x₁ = - 10/10

x₁ = - 1

Solución : (- 2/5; - 1)
