    Set y = 0 and solve for x

    \[y=\frac{ 2-\sqrt{x} }{ 5x }\] is it this

    Ok let y = 0 and solve for x as I suggested

    \[\frac{ 2-\sqrt{x} }{ 5x }=0\]

    So 5x=2-√x

    Not quite, remember you have to multiply both sides by 5x, so we have 5x * 0 = 0 right? So \[2-\sqrt{x}=0\]

    Thank you! I just couldn't see what i was missing but its multiplication of both sides not subtraction -.-

    -√x = 2 square both sides -x = 4 x+-4

    x = -4

    Well it would be better if you just move \[-\sqrt{x}\] to the right side so we have \[2-\sqrt{x}=0 \implies 2 = \sqrt{x} \implies x = 2^2 = 4\]
