Press Space for standard equation, z for quadratic formula, or x for vertex formula. Press up arrow to re-load the last standard equation, down for the formula, and right for the vertex equation. Leave the (a/b/c)-2's blank if there is no second equation you are comparing. All by me try a=2,b=16,c=24 :) 3/26/2018: You can now press 1-9 to quick scroll to each of the possibilities (If there are more than one) - added custom variables 3/22/2018: Added the "difference of squares". Made it so it gives you every possible option based off all the factors. 1/3/2018: Improved quadratic Formula calculation to auto-solve square roots multiplications and i values.
