Re write a quadratic function in standard form

Solution Step 1 Put the equation in standard form. I try to help them construct a diagram that shows this.

quadratic equation

A quadratic equation is a polynomial equation that contains the second degree, but no higher degree, of the variable. In other words, the first and third terms are perfect squares.

This applies the above theorem, which says that at least one of the factors must have a value of zero. Note that in this example we have the square of a number equal to a negative number.

Add - 3 to both sides. You now have the necessary skills to solve equations of the second degree, which are known as quadratic equations.
