Question

como se resolve com a forma de bhaskara?

1-x²=0

Answer 1

1 - x ² = 0
- x² + 1 = 0
a = -1
b = 0 
c = 1
Δ = b² - 4 a .c
Δ = 0² - 4 . -1 . 1
Δ = 0 + 4
Δ = 4
\/¨4=2
x = -b +ou-2/2.-1
x = -0 + ou- 2 / -2
x = +2/-2 → - 1
x = -2/-2 → 1
S = {-1,1}

Answer 2

Ola Zznada

1 - x² = 0

x² - 1 = 0

a = 1
b = 0
c = -1

delta
d² = b² -4ac = 0 - 4*1*-1 = 4
d = 2

x1 = (-b + d)/2 = (-0 + 2)/2 = 1
x2 = (-b - d)/2 = (-0 - 2)/2 = -1
