Answer: x = ± 2 √3 ; or, write as: x = ± 3.464 .
__________________________________________________
Given: 12 – x² = 0 ;
Multiply BOTH side by "-1" ;
__________________________________________________
-1 (12 – x² = 0) ;
to get:
-12 + x² = 0 ;
Rewrite as:
x² - 12 = 0 ;
Add "12" to both sides; to get:
x² = 12
Take the square root of each side:
√(x²) = ±√(12)
x = ± √(12)
_________________________________________________
√(12) = √(4) * √(3) = 2 √(3)
√(12) = 3.4641016151377546 ; round to: 3.464 .
