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!

I assume you mean either 3x2 -x + 20 = 0, or 3x2 -x - 20 = 0. Use the quadratic formula, replacing a = 3, b = -1, and c = 20 (or -20).

How many roots does a quadratic equation in one variable have?

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.

How do you solve the equation 5x-93x 11 and are these simultanous equation if there are no answers on the end of each equation?

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
