$ax^2 = bx + c$

$ax^2 + bx + c = 0$ (correct)

$ax + bx^2 + c = 0$

$ax^2 + bx = c$

$a eq 0$ (correct)

$a < 0$

$a > 0$

$a = 0$

$x^2 + 2x + 1 = 0$

$x^2 - 9 = 0$

$2x^3 + 3x^2 + 4x + 5 = 0$ (correct)

$4x^2 + 7x - 3 = 0$

The standard form of a quadratic equation is ax^2 + bx + c = 0, where a, b, and c are constants and a ≠ 0.
The condition for 'a' in the standard form of a quadratic equation is a ≠ 0, which means 'a' should not be equal to zero.
x^2 + 2x + 1 = 0 is a quadratic equation, but x^2 + 2x + 1 = 2x is not a quadratic equation, as it does not equate to zero.
