x2-4x+4 = 0
(x-2)(x-2) = 0
x = 2 or x = 2 It has two equal roots.
x = 2 and x = 4
Using the quadratic equation formula:- x = -4.706950048 and x = 0.849071913
It is a quadratic equation in X, with two real roots.
The discriminant is -27 and so there are no real roots.
Using the discriminant formula for a quadratic equation k has a value of 8/25 or maybe 0.
The roots are: x = -5 and x = -9
This quadratic equation has no real roots because its discriminant is less than zero.
x = 2 and x = 4
Using the quadratic equation formula:- x = -4.706950048 and x = 0.849071913
If you mean b^2 -4ac then it is the discriminant of a quadratic equation. If the discriminant equals 0 then the equation has 2 equal roots. If the discriminant is greater than 0 then the equation has 2 different roots. If the discriminant is less than 0 then it has no real roots.
It is a quadratic equation in X, with two real roots.
Use the quadratic formula, with a = 1, b = -3, c = 2.
The discriminant is -27 and so there are no real roots.
Using the discriminant formula for a quadratic equation k has a value of 8/25 or maybe 0.
It is a quadratic equation with one unknown variable, x which has no real roots.
2x2 + 3x - 20 = (x + 4)(2x - 5).
(x - 1)(x - 11) x = 1,11
