Question

qual e a fórmula de Bhaskara de 2x²+2x-24=0​

Answer 1

Resposta:

2x² - 2x - 24 = 0

a = 2

b = -2

c = -24

Δ = b² - 4ac

Δ = (-2)² - 4 * 2 * (-24)

Δ = 4 + 192

Δ = 196

   

     x = - b ± √Δ / 2a

     x = - (-2) ± √196 / 2 * 2

     x = 2 ± 14 / 4

     x' = 2 - 14 / 4 = -12 / 4 = -3

     x'' = 2 + 14 / 4 = 16 / 4 = 4

S = {-3, 4}
