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
It's ax squared x bx x c = 0 So (ax x ax) x bx x c = 0 This is the quadratic formula, then you'll move onto the quadratic equation.
2x^2 + 8x + 3 = 0
x2-5-4x2+3x = 0 -3x2+3x-5 = 0 or as 3x2-3x+5 = 0
This equation is referred to the type of math known as Quadratics, and is used to find the probela ( probela is a high curve ark , a type of shape) PLEASE SEE, don't look up Quadratics on answers.com, made mistake on equation to find probela.
It is: 3x2+6x-11 = 0
a = 0, b = 0.
The equation ax2 + bx + c = 0, where a != 0 is called quadratic.
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
It's ax squared x bx x c = 0 So (ax x ax) x bx x c = 0 This is the quadratic formula, then you'll move onto the quadratic equation.
The graph of the first form passes through the origin while the second does not - unless c = 0.

Ax^2 + bx + c = 0
A discriminant that is less than zero.
ax^2+bx+c=0 is the standard form of a quadratic function.
2x^2 + 8x + 3 = 0
