a*x + \/  3 - 2*x - x   = 4*a + 2
$$a x + \sqrt{- x^{2} + \left(3 - 2 x\right)} = 4 a + 2$$
Solución detallada
Tenemos la ecuación
$$a x + \sqrt{- x^{2} + \left(3 - 2 x\right)} = 4 a + 2$$
$$\sqrt{- x^{2} - 2 x + 3} = - a x + 4 a + 2$$
Elevemos las dos partes de la ecuación a la potencia 2
$$- x^{2} - 2 x + 3 = \left(- a x + 4 a + 2\right)^{2}$$
$$- x^{2} - 2 x + 3 = a^{2} x^{2} - 8 a^{2} x + 16 a^{2} - 4 a x + 16 a + 4$$
Transpongamos la parte derecha de la ecuación miembro izquierdo de la ecuación con el signo negativo
$$- a^{2} x^{2} + 8 a^{2} x - 16 a^{2} + 4 a x - 16 a - x^{2} - 2 x - 1 = 0$$
Es la ecuación de la forma
a*x^2 + b*x + c = 0

La ecuación cuadrática puede ser resuelta
con la ayuda del discriminante.
Las raíces de la ecuación cuadrática:
$$x_{1} = \frac{\sqrt{D} - b}{2 a}$$
$$x_{2} = \frac{- \sqrt{D} - b}{2 a}$$
donde D = b^2 - 4*a*c es el discriminante.
Como
$$a = - a^{2} - 1$$
$$b = 8 a^{2} + 4 a - 2$$
$$c = - 16 a^{2} - 16 a - 1$$
, entonces
D = b^2 - 4 * a * c = 

(-2 + 4*a + 8*a^2)^2 - 4 * (-1 - a^2) * (-1 - 16*a - 16*a^2) = (-2 + 4*a + 8*a^2)^2 - (-4 - 4*a^2)*(-1 - 16*a - 16*a^2)

La ecuación tiene dos raíces.
x1 = (-b + sqrt(D)) / (2*a)

x2 = (-b - sqrt(D)) / (2*a)

o
$$x_{1} = \frac{- 8 a^{2} - 4 a + \sqrt{- \left(- 4 a^{2} - 4\right) \left(- 16 a^{2} - 16 a - 1\right) + \left(8 a^{2} + 4 a - 2\right)^{2}} + 2}{- 2 a^{2} - 2}$$
$$x_{2} = \frac{- 8 a^{2} - 4 a - \sqrt{- \left(- 4 a^{2} - 4\right) \left(- 16 a^{2} - 16 a - 1\right) + \left(8 a^{2} + 4 a - 2\right)^{2}} + 2}{- 2 a^{2} - 2}$$
