Answer:

Step-by-step explanation:
For example, we'll use this quadratic equation.

To understand how to plug it into the formula we need to know what each term represents.

So the equation above would be put into the formula like this.

Then we would solve

Now, the equation will branch off into one that solves when addition and one when subtraction.

So x={-3, -2} (-3 and -2)
counterexample.
One way to show that a statement is NOT a good definition
is to find a counterexample. In description, counterexample is an exception to
a “proposed general rule or law”. Philosophically, counterexample somehow
generalizes a set of ideas or a notion declared in its position. For example,
all colors are white. Therefore it is wrong to say that red, orange, blue or
any other “color” is not a color by which the statement declared itself.
Moreover, in mathematics counterexamples are utilized frequently
to testify theorems' limitations.
