# Completing the square

Maths Tables 1 - 20 Completing The Square Method A polynomial equation with degree equal to two is known as quadratic equation. A quadratic equation in its standard form is represented as: Since,the degree of the above written equation is two; it will have two roots or solutions. Selecting "AUTO" in the variable box will make the calculator automatically solve for the first variable it sees. Quick-Start Guide When you enter an equation into the calculator, the calculator will begin by expanding simplifying the problem. Next, it will attempt to solve the equation by using one or more of the following: Use the following rules to enter equations into the calculator.

Variables Any lowercase letter may be used as a variable.
