    Alternatively, and more painfully:

    With x=\sqrt{u},

    (x^3+4x+3)^2=x^6+8x^4+6x^3+16x^2  +24x+9 = \\ u^3+8u^2+6x^3+16u+24x+9

= u^3+8u^2+16u+9 + 6(x^3+4x) = \\ u^3+8u^2+16u+9 + 6(-3) =u^3+8u^2+16u-9

    It's OCR. Subtract 3 from both sides before squaring.

    shurley if you sub u into the equation it equals
     u^{\frac{3}{2}}+4u^{\frac{1}{2}}  +3=0

    Then move the three over and square
     (u^{\frac{3}{2}}+4u^{\frac{1}{2}  })^2=-3^2
    then expand
     u^3+8u^2+16u=9

    sorry for the slow reply I'm really bad at LaTeX
    Get in lad. Wawawheewa.
