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.

∙ 8y agoI 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).

What is true about a quadratic equation when the discriminant of the equation is positive?
It will then have 2 different roots If the discriminant is zero than it will have have 2 equal roots
What are the roots of the quadratic equation below?
That depends on the equation.
How many real roots do we have if the polynomial equation is in degree six?
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.
What can the discriminant tell you about a quadratic equation?
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.
If the discriminant of an equation is zero What is true of the equation?
That its roots (solutions) are coincident.
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.
What are the roots of the quadratic equation y equals 2x2 plus 3x-20?
2x2 + 3x - 20 = (x + 4)(2x - 5).
What is the answer to 3x2x 4?
3*2*4 = 24
What is true about a quadratic equation when the discriminant of the equation is positive?
It will then have 2 different roots If the discriminant is zero than it will have have 2 equal roots
What are the roots of the quadratic equation below?
That depends on the equation.
How many roots does a quadratic equation?
2 roots
The solutions of an equation are often called what?
The roots of the 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
What is the answer -2x 48-3x-3x2x 6 3x?
the answer is 6
What are quadratic equations with real roots?
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.
What are the roots of a quadratic equation called?
Either "roots" or "solutions".
How many real roots do we have if the polynomial equation is in degree six?
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.
