Question

utilize a fórmula de bhaskara:
ax² + bx + c=
x² - 10x + 24=

Answer 1

-x² + 10x - 24 = 0

a = -1; b = 10; c = -24

Delta:

Δ = b² - 4ac

Δ = 10² - 4 * (-1) * (-24)

Δ = 100 - 96

Δ = 4

Bhaskara:

x = - b ± √Δ / 2a

x = - 10 ± √4 / 2 * (-1)

x = - 10 ± 2 / -2

x' = - 10 - 2 / -2 = -12 / -2 = 6

x'' = - 10 + 2 / -2 = -8 / -2 = 4

S = {4, 6}
