5 times 2 square equals 20 minus 29 equals -9

That won't factor neatly, so we apply the quadratic formula. x = -8 plus or minus 2 times the square root of 5 x = -3.5278640450004204 x = -12.47213595499958

âˆš(6x) - 3 - 3âˆšx = 1 âˆš(6x) -3âˆšx = 4 âˆšx = 4/(âˆš6 - 3) = -4(âˆš6 + 3)/3 = 16/9*(15+6âˆš6) = 16/3*(5+2âˆš6) = 52.8, approx.
