A discriminant that is less than zero.
It is the general form of a quadratic equation.
A quadratic equation.
x^2+4x+7
ax2 + bx +c is an expression, not an equation. It cannot, therefore, have a solution. If the question concerns the equation ax2 + bx + c = 0 then the answer is ax2 - 16ax + 64a = 0 for any a other than 0.
A discriminant that is less than zero.

2x^2 + 8x + 3 = 0
ax2 + bx +c is an expression, not an equation. It cannot, therefore, have a solution. If the question concerns the equation ax2 + bx + c = 0 then the answer is ax2 - 16ax + 64a = 0 for any a other than 0.
The equation ax2 + bx + c = 0, where a != 0 is called quadratic.
ax^2+bx+c=0 is the standard form of a quadratic function.
ax2 +bx + c = 0
y = ax2 + bx + c
Two: one is 0, the other is -b/a ax2 + bx + c = 0, but c = 0 ⇒ ax2 + bx + 0 = 0 ⇒ ax2 + bx = 0 ⇒ x(ax + b) = 0 ⇒ x = 0 or (ax + b) = 0 ⇒ x = -b/a
