Solve (u-3)^2+4=16 where u is a real number.
Round your answer to the nearest hundredth.
If there is more than one solution, separate them with commas.
If there is no solution, click on "No solution".
(u-3)^2 + 4 = 16
(u-3)^2 = 12
Taking the square root of both sides:
u-3 = ±√12
u-3 = ±2√3
Therefore, u = 3 ± 2√3
Rounded to the nearest hundredth:
u = 3 + 2√3 ≈ 6.46,
u = 3 - 2√3 ≈ -0.46
