3x = √ (-6x + 8)
(3x) ² = (√ (-6x + 8)) ²
9x² = - 6x + 8
9x² - 9x² = - 9x² - 6x + 8
0 = - 9x² - 6x + 8
x = - (-6) ± √ ((-6) ² - 4 (-9) (8))
2 (-9)
x = 6 ± √ (36 + 288)
-18
x = 6 ± √ (324)
-18
x = 6 ± 18
-18
x = 6 + 18 U x = 6 - 18
-18 - 18
x = 24 U x = - 12
-18 - 18
x = - 1¹/₃ U ²/₃
Solution Set: {-1¹/₃, ²/₃}

3x=√8-6x
Simplifies to
3x=-6x+2.828427
Add 6x to both sides
.
3x+6x=-6x+2.828427+6x
9x=2.828427
Divide both sides by 9.
9x/9=2.828427/9
x=0.31427
