**How to tell when an equation with two variables has only**

When there is only one variable, polynomial equations have the form P(x) = 0, where P is a polynomial, and linear equations have the form ax + b = 0, where a and b are parameters. To solve equations from either family, one uses algorithmic or geometric techniques that originate from linear algebra or mathematical analysis .... For exactly one positive root of cubic equation, the other two roots may either be both non-positive (distinct or equal, doesn't matter) or complex roots in pairs. 1.

**Show that this equation only has one solution Physics Forums**

Just as a quadratic equation may have two real roots, so a cubic equation has possibly three. But unlike a quadratic equation which may have no real solution, a cubic equation always has at least one real root. If a cubic does have three roots, two or even all three of them may be repeated....2014-08-10Â Â· One solution, no solution, or infinitely many solutions. Find out how to determine if a solution is consistent or inconsistent. Dependent or independent. One solution, no solution, or infinitely

**Show that this equation only has one solution Physics Forums**

2018-10-18Â Â· Show that the equation arctan(x) = x^2 have at least one solution. Then argue why the equation only has one, positive solution r. 2. Relevant equations 3. The attempt at a solution I know how to prove that the equation has at least one solution (IVT), but I do not know how to show the second part. If the derivative is strictly positive/negative I know the answer, but that is not the case here. how to turn off chime on 2016 dodge 2500 The equation can have two complex number solutions. There are no real number solutions. There are no real number solutions. Don't worry; there's an easy way to find out how many solutions there are before you even start using the formula..

### 2017-11-29Â Â· Does anyone know if there is a way to tell that an equation with two variables has only one unique solution? If so, is there to quickly generate the solution besides simple guess and test? Thanks in advance.

- Identifying the solution set of an equation usually involves three steps: First, you solve the equation for one variable in terms of the other; the convention is to solve for y in terms of x.

- If a system of linear equations has at least one solution, it is consistent. If the system has no solutions, it is inconsistent . If the system has an infinity number of solutions, it is dependent .
