Everytime you feel like you are handling your workload and getting more done because of the increased hours you are putting in, you should remind yourself of this equation:

In elementary algebra, the quadratic formula is a formula that provides the solution(s) to a quadratic equation. There are other ways of solving a quadratic equation instead of using the quadratic formula, such as factoring (direct factoring, grouping, AC method), completing the square, graphing and others. Given a general quadratic equation of the form ax²+bx+c=0 with x representing an unknown, a, b and c representing constants with a ≠ 0, the quadratic formula is: x=(-b±√(b²-4ac))/2a where the plus–minus symbol "±" indicates that the quadratic equation has two solutions. In algebra, a quadratic equation (from the Latin quadratus for "square") is any equation that can be rearranged in standard form as ax²+bx+c=0 where x represents an unknown, and a, b, and c represent known numbers, where a ≠ 0. If a = 0, then the equation is linear, not quadratic, as there is no ax² term. The numbers a, b, and c are the coefficients of the equation and may be distinguished by calling them, respectively, the quadratic coefficient, the linear coefficient and the constant or free term.

Thanks loads for this very informative example. I recently purchased a Casio fx-991EX through Amazon because my previous calculator, a Casio FX-115 ( the for-runner of this one) died after 20 years. The documentation that comes with the Fx-991EX is not the best. I’ve been trying for several days to solve even the simplest quadratic equations with no success. They wanted me to enter the data using a “Coeffiicent editor” which was complex. I was on the verge of returning my calculator back to Amazon before my 30 days return period ran out. Then I got the idea of googling online to see if anyone else had a similar problem. I found your example ONLINE and no longer am planning to return my calculator.Remember all those riddles on Facebook or Instagram, you know, the ones where three apples are equal to 30, an apple and two bananas are equal to 18, and a banana minus a coconut equal to two, and you had to calculate how much the apple, banana, and coconut are worth? That is what the mathematicians call a system of linear equations. "But how? Mathematicians don't use apples and bananas, do they?" Well, they too like to keep the doctor away and bite into an apple from time to time, but you're right, they don't calculate in apples. However, it doesn't make any difference if you right "Three apples equal to 30," or (Source: www.omnicalculator.com)
