Question

3 x elevado a 2 mais 5x menos 6 x= igual a menos 2

Answer 1

3x² + 5x - 6x = 2
3x² -x - 2 = 0

BHASKHARA

x = - b ± √b² - 4ac / 2a

x = - (-1) ± √(-1)² - 4 × 3 × (-2) / 2 × 3

x = 1 ± √1 + 24 / 6

x = 1 ± √25 / 6

x = 1 ± 5 / 6


x' = 1 + 5 / 6
x' = 6 / 6
x' = 1


x" 1 - 5 / 6
x" -4 / 6
x" -2/3
