Question

3(x-4)^2-4=146

Answer 1

\[(x-4)^{2}=50\]\[3(x-4)^{2}=146+4\]\[3(x-4)^{2}-4=146\]
\[3(x-4)^{2}=150\]
\[(x-4)^{2}=150/3\]
Take square roots on both sides,
\[x-4=\sqrt{50}\]
\[x=4\pm5\sqrt{2}\]

Answer 2

3(x-4)^2-4=146
3(x-4)^2 = 146 + 4
(x -4) ^2 = 150/3
->(x-4) = sqrt (50)
=>x = 4 +/- 7.07 = -3.07, 11.07
