9x2 - 12x + 4 = 0 is of the form ax2 + bx + c = 0 where the discriminant, D, can be found by
D = b2 - 4ac
First, you find the values of a, b and c:
a = 9
b = -12
c = 4
Now you can find D:
D = (-12)2 - (4)(9) = 144 - 36 = 108
D = 108
The discriminant is 0.
The discriminant formula. b2 - 4ac 32 - 4(1)(8) 9 - 32 = - 23 ===========This shows no real roots to this function.
The discriminant is 0.
no
You need another equation.
The discriminant is 33.
The discriminant is -11.
The discriminant is 0.
The discriminant is -167.
It is: 25-4(8*6) = -167
The discriminant is 9.
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.
The discriminant is -27 and so there are no real roots.
It has no solutions because the discriminant of the quadratic equation is less than zero.
A discriminant is based on the differences between roots of an equation. A linear equation, such as the onle in the question, has only one root and therefore cannot have a discriminant.
The discriminant is -439 and so there are no real solutions.
The discriminant is 25.
