Question 553736
If these are the solutions, I can say
{{{ x = -3.3 }}} and
{{{ x = .3 }}}
-----------
It is also true
{{{ x + 3.3 = 0 }}}
{{{ x - .3 = 0 }}}
-----------
Now multiply left sides and
set equal to zero
{{{ ( x + 3.3 )*( x - .3 ) = 0 }}}
{{{ x^2 + 3.3x - .3x - .99 = 0 }}}
{{{ x^2 + 3x - .99 = 0 }}}
The quadratic equation is
{{{ f(x) = x^2 + 3x - .99 }}}
