Question

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

Answer 1

Answer:

x = ± 2$\sqrt{3}$

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 = ±$\sqrt{12}$

  = ± $\sqrt{4(3)}$ = ± 2$\sqrt{3}$
