Question 560583
{{{ x = 9 }}}
{{{ x = 27 }}}
rewrite these as:
{{{ x - 9 = 0 }}}
{{{ x - 27 = 0 }}}
and
{{{ ( x - 9 )*( x - 27 ) = 0 }}}
{{{ x^2 - 36x + 243 = 0 }}}
{{{ f(x) = x^2 - 36x + 243 }}}
----------------------
{{{ ( x - 4 )*( x - 16 ) = 0 }}}
{{{ x^2 - 20x + 64 = 0 }}}
{{{ f(x) = x^2 - 20x + 64 }}}
