Question

resuélvelas

usando la fórmula general

2x^2 + 2x + 3 = 0

5x^2 + 2x = 0

36x – x^2 = 62
porfaaaaa

Answer 1

Explicación paso a paso:

2x² + 2x + 3 = 0

(2/2)x² + (2/2)x + (3/2) = 0/2

1x² + 1x + 3/2 = 0

x = [-2+√(2²-4×2×3)]/2×2

x = [-2+√(4-24)]/4

x1 = [-2+√-20]/4

x2 = [-2-√-20]/4

Raíz de -20 no existe, es un número imaginario.

5x² + 2x = 0

x(5x+2)=0

x=0

5x+2=0

x=(-2/5)

X1= 0

X2 = -2/5

x² - 36x + 62 = 0

x = [36+√(-36)²-4×1×62]/2

x = [36+√36²-128]/2

x = [36+√1048]/2

x = [36+2√262]/2

x1 = 18+√262

x2 = 18-√262
