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.

MathFollow the steps 1)4) 1) First expand out the bracketed term: `x1 (x1)^2 = x 1  (x1)(x1) ` `= x  1  (x^2  x  x + 1)` `= x  1  (x^2  2x + 1)` 2) Now gather terms: `x  1  (x1)^2 =...

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.`...
