Answer 5

I think she's new here, so I guess she can have some tolerance.
The quadratic formula is the "solution" of a complete quadratic function.
It puts in evidence the roots of the function, in other words, where it cuts the x-axis.
It looks like this:
\[x=\frac{ -b \pm \sqrt{b^2-4ac} }{ 2a }\]
the numbers inside the square root is called the "discriminant" and it tells us wether the function is tangent, secant or non concurrent to the x-axis.
The discriminant is written as delta, and reprsents the variables inside the square root:
\[\Delta = b^2-4ac\]
