Quadratic EquationsA quadratic function, is a polynomial function of the form `f(x) = ax^2 + bx + c, x!= 0.` Therefore, if your function has an `"x^2"` term, then it is a quadratic function.

MathAlternatively, factor out an `x1` right away. `x1(x1)^2=(x1)(1(x1))` `=(x1)(1x+1)=(x1)(2x).`

MathThere are several methods and variations of these basic methods for factoring quadratics. If we start from a product of the form `(x+a)(x+b)` and expand it, we get `(x+a)(x+b)=x^2+(a+b)x+ab.`...
