Question 53926
Any equation in the form {{{ax^2+bx+c}}} graphs to a parabola.  A lot of times those equations can also be factored.  Your equation cannot be factored as there are no two numbers when multiplied together is 1 and when added together is -4.  So, to solve it, you'll need to use {{{x = (-b +- sqrt( b^2-4*a*c ))/(2*a)}}}.  The graph looks like:
{{{graph(200,200,-5,5,-2,10,2x^2-4x+1)}}}
