What are the solutions of 12 – x2 = 0?
O x=273 and x = -213
O x= 3,
and x = -3/2
x = 4/5 and x = -4/3
x = 6 and x = -6

Respuesta :

Answer:

x = ± 2[tex]\sqrt{3}[/tex]

Step-by-step explanation:

Given

12 - x² = 0 ( add x² to both sides )

12 = x² or

x² = 12 ( take the square root of both sides )

x = ±[tex]\sqrt{12}[/tex]

  = ± [tex]\sqrt{4(3)}[/tex] = ± 2[tex]\sqrt{3}[/tex]
