how to do standard form of a quadratic function
The general form of a quadratic function can be written as: f(x) = a*x2 + b*x + c where a, b and c are constants, and a is not zero.
If you mean the standard form of a quadratic equation, then it's this:
x^2 - 2x +1 = 0, the signs of +, - could be different.
