By first executing your code you should obtain the following: Welcome to Quadratic Solver for f(x)-ax**2+bx+c Enter value for a: 2 Enter value for b: 3 Enter value for c: 1 Equation is: f(x)-2.0x* 2+3.0x+1.0 Press Enter to continue. . . By order, (1) the code is printing the welcome statement "Welcome to Quadratic Solver for f(x)-ax**2+bx+c" (2) it is then skipping a line, (3) ask the user to enter a value for a, for b and for c (we use 2, 3, 1, respectively, for this example), (4) skip a line again, (5) return the expression of the quadratic function f (x), (6) skip a line, (7) wait for the user to press Enter/Return before to process further What you need to implement 1. A function my quad equation that should accept a,b,c and should display or return the equation (String). The input coefficients a,b,c are considered float and could be converted to string before display 2. the Press Enter to continue... wait instruction (including 'line skipping'), could simply be achieved by adding this line to the program temp input (" Press Enter to continue ") # wait where temp is just a temporary unused variable
