Aquadratic equation in standard form is written ax^2+bx+c=0, where a, b and c are real numbers and a is not zero. true or false

This statement is true.  For example:

 is an example of a quadratic equation in standard form.  a, b, and c are all real numbers, while a ≠ 0.

is another example.  a, b, and c are real numbers (b = 0), and a ≠ 0.

would not be an example of a quadratic equation in standard form.  a is not a real number.

is not an example because a = 0.

21, i'm pretty sure it's right lol
