Iteration is a way of solving equations. You would usually use iteration when you cannot solve the equation any other way. An iteration formula might look like the following: x n+1 = 2 + 1. x n . You are usually given a starting value, which is called x 0. If x 0 = 3, for example, you would substitute 3 into the original equation ...

WebHere's how: you can tell about the nature of the roots by evaluating the discriminant (delta), Δ = b 2 - 4ac upon plugging in it, a, b, and c of the quadratic equation ax 2 + bx + c = 0. If Δ = 0, the roots are real and equal; if Δ > 0, the roots are real and unequal; if Δ < 0, the roots are unreal or complex.
