Roots of cubic equation?
There is a formula, but it is very difficult. I will give you a link to it. http://en.wikipedia.org/wiki/Cubic_equation
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.
Are there equations that are neither linear nor quadratic?
There are many equations that are neither linear nor quadratic. A simple example is a cubic equation, such as y = x3, or a logarithmic equation, such as y = ln(x).
Can bisection method give us two answers for different intervals for same equation i have equation 2x3 plus x2-20x plus 12 equals 0. i have to find real root upto 3 correct decimal places. I chose int?
Yes. A cubic equation can have 3 real roots. Depending on their size, each of three intervals could contain a root. In that case different intervals must give different roots.Yes.

What statement must be true of an equation before you can use the quadratic formula to find the solutions?
The quadratic formula can be used to find the solutions of a quadratic equation - not a linear or cubic, or non-polynomial equation. The quadratic formula will always provide the solutions to a quadratic equation - whether the solutions are rational, real or complex numbers.
Equation for solving a cubic equation?
Put simply, the equation for solving a cubic equation is x2 + 2ax +b = (x+a)2 + b-a2. This leads to x = -a +/- (a2 -b)1/2.
What is the equation to convert milliliters to cubic meters?
mL x 0.000001 = cubic meters
How many real solutions does a cubic equation have?
A cubic has from 1 to 3 real solutions. The fact that every cubic equation with real coefficients has at least 1 real solution comes from the intermediate value theorem. The discriminant of the equation tells you how many roots there are.
What is the equation for converting cubic inches to cubic yards?
1 yd = 36 inches, thus 1 cubic yard = 46,656 cubic inches
What is the equation of cubic meter to gallon?
1 cubic meter = 264.17 US fluid gallons
How Do you solve a cubic equation by trisecting an angle?
The classical problem of angle trisection cannot be solved. If it were possible, it would provide the solution to a cubic equation. (-but it isn't and it won't!)
By which process does a cubic equation draw into the graph?
By the process of plotting.
What is x3 equal 4x?
It is a cubic equation in the variable x.
Is the equation for one yard 3x3x3?
If the question is, how many cubic feet are in a cubic yard, then you would get that result, 3'x3'x3' = 27 cubic feet.
How do you convert 7.703 cubic meters per second to cubic feet per second?
Use this equation: cubic meters per second x 35.3147 = cubic feet per second
Is it a cubic trinomial?
A cubic trinomial is an algebraic expression with three terms, where the highest power of the variable is 3. For example, (x^3 + 2x^2 - 3x) is a cubic trinomial. If the expression you're referring to fits this criteria, then yes, it is a cubic trinomial.
Is x3-27 equals 0 a quadratic equation?
No, it's a cubic equation. A quadratic equation contains, as its term raised to the highest power, a square. Example: x2. A cubic equation contains, as its term raised to the highest power, a cube. Example: x3. A quartic equation contains, as its term raised to the highest power, a term raised to the fourth power. Example: x4. Quintic, x5. And so, on.
