Question

formula de baskara
-x²-3×=0​

Answer 1

-x² -3x = 0

a = -1

b = -3

c = 0

_______________

Δ = b² - 4 . a . c

Δ = (-3)² - 4 . (-1) . 0

Δ = 9 + 0

Δ = 9

_______________

x = ( -b +- √Δ) / 2 . a

x = ( 3 +- √9) / 2 . (-1)

x = ( -3 +-3) / -2

x' = ( -3 + 3) / -2

x' = 0/-2

x' = 0

x'' = ( -3 - 3) / -2

x'' = -6/-2

x'' = 3

_____________
