Question

Resolva as equções incompletas -ײ+6×=0

Answer 1

-x² +6x = 0

Δ= 6² - 4 . -1 . 0

Δ= 36 - 0

Δ= 36

-6 +- √36 ÷ 2 . -1

-6 +- 6 ÷  -2

x1= -6 + 6 ÷ -2

x1= 0 ÷ 2

x1= 0

x2= -6 -6 ÷ -2

x2= -12 ÷ -2

x2= +6

Answer 2

Olá....

- x² + 6x = 0

x(-x + 6) = 0

x' = 0

- x + 6 = 0

- x = - 6 ( - 1)

x" = 6

S = {x' = 0 e x" = 6}

Bons estudos.
