Question 355165
You can use {{{ formula }}} notation to insert nice looking formulas into the text of your solution. Example: {{{x = (-b +- sqrt( b^2-4*a*c ))/(2*a) }}} would result in this formula: . Create a graph by saying {{{ graph( 300, 200, -6, 5, -10, 10, x-2, x^2/10-x) }}} (graph 300x200 pixels, x from -6 to 5, y from -10 to 10, of TWO functions x^2 and x^2/10-x).
