A cubic equation, which is typically in the form ( ax^3 + bx^2 + cx + d = 0 ), always has three roots in the complex number system, counting multiplicities. These roots could be all real, or one real root and two complex conjugate roots depending on the discriminant. Thus, while there are always three roots in total, their nature (real or complex) can vary.

What are the operations on cubic root?
The main operation on the cubic root is finding the value of the cubic root of a number. This is commonly represented by using the symbol ∛, such as ∛x. Other related operations include estimating the value of the cubic root, solving equations involving cubic roots, and using properties of cubic roots in mathematical calculations.
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 symbol for an irrational number?
There is no special symbol for an irrational number. However, it is known that many square roots, cubic roots, etc., as well as some special numbers such as pi and e, are irrational.
What are the 3 examples of irrational numbers?
Pi, e, most square roots, most cubic roots, etc.
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 find out cubic roots?
Take the logarithm of your number, divide it by 3 then take the antilog.
How many x-intercepts can a cubic function have?
you can have either one or three x-intercepts, but now 2. because two real roots means 1 imaginary root which is not possible since imaginary roots come in pairs (2,4,6,8...)
What are some similarities and differences between quartic and cubic functions?
The similarities are that they are polynomial functions and therefore continuous and differentiable.A real cubic will has an odd number of roots (and so must have a solution), a quartic has an even number of roots and so may have no solutions.
What are the imaginary cube roots of -125?
This can be done easily if you use polar coordinates. I did all of the following calculations in my head, without resorting to a calculator: One of the cubic roots of -125 is -5. That is the same as 5, at an angle of 180 degrees. The other two cubic roots also have an absolute value of 5, and each cubic root has an angle of 120 degrees to the other cubic roots. In other words, the complex roots are 5 at an angle of 60 degrees, and 5 at an angle of -60 degrees. If you want to convert this to rectangular coordinates (i.e., show the real and the imaginary parts separately), use the P-->R (polar to rectangular) conversion, available on most scientific calculators.
