What is the value of b2-4ac equal to 0?
It is the value of the discriminant of a quadratic equation.
What is the value of k when 4x squared plus kx plus 9 equals 0?
Using the discriminant for a quadratic equation the value of k works out as plus or minus 12.

Some symbols not visible. Please resubmit using words eg "plus", "equals" etc
What are the roots of quadratic equation?
That depends on the value of its discriminant if its less than zero then it has no real roots.
What are the possible values of k in the quadratic equation x squared plus 5kx plus 2k equals 0 which has equal real roots?
Using the discriminant formula for a quadratic equation k has a value of 8/25 or maybe 0.
What is the value of b2-4ac equal to 0?
It is the value of the discriminant of a quadratic equation.
If the discriminant of a quadratic equation is zero and one root of the equation is 5 what is the value of the other root?
It too will have a value of 5
Which values for a b or c can you not use the quadratic equation?
a = 0. That is because a = 0 implies that there is no quadratic term and so the equation is not a quadratic!There may be some who make claims depending on the value of the discriminant (which is b2-4ac). That is true only for elementary mathematics. In more advanced mathematics (complex analysis), the quadratic equation can be used in all cases except when a = 0: the value of the discriminant is irrelevant.a = 0.

Yes and they will be of equal value
Find the value of the discriminant of each equation given X2 - 5x plus 4 equals 0?
The discriminant is 9.
What is the value of the discriminant of the polynimial 4x2 plus 7x plus 4?
72-4*4*4 = -15 The discriminant is less than zero so there's no solutions to the quadratic equation.

What is the formula for finding the value of x in the quadratic equation ax2 bx c0?
Unfortunately, limitations of the browser used by Answers.com means that we cannot see most symbols. It is therefore impossible to give a proper answer to your question. However, assuming your question to find the roots or solutions of ax2 + bx + c = 0, the answer is x = [-b ± sqrt(b2 - 4ac)]/2a b2 - 4ac is called the discriminant. If the discriminant > 0 then the quadratic equation has two distinct real roots. If the discriminant = 0 then the quadratic equation has one double root. If the discriminant < 0 then the quadratic equation has two distinct complex roots that are conjugates of one another.
