Question

-x^2+12x=0
me ajudem fórmula baskara pfvvvv!!

Answer 1

-x²+12x=0

a= -1

b=12

c= 0

Δ=(b²-4ac)

Δ= (12)²-4(-1.0)=0

Δ= 144-0

Δ= 144

-b(±)√Δ / 2.a

-12±√144/2. (-1)

-12±12 / -2

x'= -12+12/ (-2) = 0

x"= -12-12/(-2) = -6

Answer 2

Olá

- x² + 12x = 0

x(-x + 12) =0

x' = 0

- x + 12 =0

- x = - 12==>(× por -1)

x" = 12

S={x'=0 e x"= 12}

Bons estudos
