    When $a \ne 0$, there are two solutions to \(ax^2 + bx + c = 0\) and they are

    $$x = {-b \pm \sqrt{b^2-4ac} \over 2a}.$$

    Excellent!!! Hey guys, there is a program called the Daum equation editor that allows one to easily write equations that look nice.

      I think you got a few "extra's" in front of the actual link, it didn't connect...

      Now, edit the formula quickly and easily expressed in your Chrome browser

        The VCCM equation is a good test.
        [TEX]
        v_{ ss }=K_{ vpl }\sqrt { \frac { P_{ s }\cdot A_{ pe }-F_{ l } }{ A_{ pe }^{ 3 }\cdot (1+\frac { { \rho }_{ v }^{ 2 } }{ { \rho }_{ c }^{ 3 } } ) } }
        [/TEX]
        [LaTex]
        v_{ ss }=K_{ vpl }\sqrt { \frac { P_{ s }\cdot A_{ pe }-F_{ l } }{ A_{ pe }^{ 3 }\cdot (1+\frac { { \rho }_{ v }^{ 2 } }{ { \rho }_{ c }^{ 3 } } ) } }
        [/LaTex]
        \[
        v_{ ss }=K_{ vpl }\sqrt { \frac { P_{ s }\cdot A_{ pe }-F_{ l } }{ A_{ pe }^{ 3 }\cdot (1+\frac { { \rho }_{ v }^{ 2 } }{ { \rho }_{ c }^{ 3 } } ) } }
        \]
        v_{ ss }=K_{ vpl }\sqrt { \frac { P_{ s }\cdot A_{ pe }-F_{ l } }{ A_{ pe }^{ 3 }\cdot (1+\frac { { \rho }_{ v }^{ 2 } }{ { \rho }_{ c }^{ 3 } } ) } }
        \begin{equation}
        v_{ ss }=K_{ vpl }\sqrt { \frac { P_{ s }\cdot A_{ pe }-F_{ l } }{ A_{ pe }^{ 3 }\cdot (1+\frac { { \rho }_{ v }^{ 2 } }{ { \rho }_{ c }^{ 3 } } ) } }
        \end{equation}

        I couldn't find an option that would allow me to paste the VCCM equation into my post. On our forum there is a button like those in the advanced editor that allows adding LaTex or Mathml equations. They are like the code, html and php buttons in the advance editor.
        I tried many options and none work.

        This is how it works on my forum

        The VCCM equation is handy for computing the maximum steady state speed of a hydraulic servo system. In reality the value calculated for the maximum steady state velocity must be reduced some what because the supply pressure usually drops during motion.
        [latex]v_{ ss }=K_{ vpl }\sqrt { \frac { P_{ s }\cdot A_{ pe }-F_{ l } }{ A_{ pe }^{ 3 }\cdot (1+\frac { { \rho }_{ v }^{ 2 } }{ { \rho }_{ c }^{ 3 } } ) } }[/latex]
        Where:
        [latex]v_{ ss }[/latex] is the maximum steady state velocity
        [latex]K_{ vpl }[/latex] is the valve flow constant computed from the valve specifications.
        [latex]P_{ s }[/latex] is the supply pressure
        [latex]A_{ pe }[/latex] is the area of the powered or pushing side of the piston.
        [latex]F_{ l }[/latex] is the load force. Subtract if opposing motion, add if aiding motion.
        [latex]{ \rho }_{ v }[/latex] is the ratio of the flow constant of the power land to the exhausting land. Normally valves are symmetrical so [latex]{ \rho }_{ v }=1[/latex]
        [latex]{ \rho }_{ c }[/latex] is the ratio of the piston's pushing area to the side that is exhausting.
