3x^2 - x + 20 = 0 doesn't factor neatly. Using the quadratic formula, we find two complex roots with imaginary solutions.
(1 plus the square root of -239) divided by 6
(1 minus the square root of -239) divided by 6
x = 0.16666 repeating + 2.576604138956718i
x = 0.16666 repeating - 2.576604138956718i
where i is the square root of negative one.
Unfortunately, the browser used by Answers.com for posting questions is incapable of accepting mathematical symbols. This means that we cannot see the mathematically critical parts of the question. We are, therefore unable to determine what exactly the question is about and so cannot give a proper answer to your question. Please edit your question to include words for symbols and resubmit. There is no equality symbol in the question, so there is no equation!
It will then have 2 different roots If the discriminant is zero than it will have have 2 equal roots
That depends on the equation.
Such an equation has a total of six roots; the number of real roots must needs be even. Thus, depending on the specific equation, the number of real roots may be zero, two, four, or six.
It can tell you three things about the quadratic equation:- 1. That the equation has 2 equal roots when the discriminant is equal to zero. 2. That the equation has 2 distinctive roots when the discriminant is greater than zero. £. That the equation has no real roots when the discriminant is less than zero.
That its roots (solutions) are coincident.
3*2*4 = 24
A quadratic equation has two roots. They may be similar or dissimilar. As the highest power of a quadratic equation is 2 , there are 2 roots. Similarly, in the cubic equation, the highest power is 3, so it has three equal or unequal roots. So the highest power of an equation is the answer to the no of roots of that particular equation.
2x2 + 3x - 20 = (x + 4)(2x - 5).
It will then have 2 different roots If the discriminant is zero than it will have have 2 equal roots
the answer is 6
I assume you have : 5x - 9 = 3x + 11This is a single algebraic expression.Subtract 3x from both sides.5x - 9 - 3x = 3x + 11 - 3x2x - 9 = 11Add 9 to both sides :2x - 9 + 9 = 11 + 92x = 20x = 10
That depends on the equation.
2 roots
The roots of the equation
If the discriminant of the quadratic equation is zero then it will have 2 equal roots. If the discriminant of the quadratic equation is greater than zero then it will have 2 different roots. If the discriminant of the quadratic equation is less than zero then it will have no roots.
Either "roots" or "solutions".
