Equations
Again and again you will work with equations in mathematics. For this you have to know the different types and their solution methods.
Types of equations
| Type | Example |
|---|---|
| Linear equations | $3x+6=0$ |
| Quadratic equations | $2x^2-4x+8=0$ |
| Cubic equations | $x^3+5x^2+4x+2=0$ |
| Fractional equations | $\frac{5x}{3x+15}=10$ |
| Exponential equations | $3^x=27$ |
| Logarithm equations | $\log x=2$ |
Solve equations
The solution method depends on the type of equation.
| Type | Solution method |
|---|---|
| Linear equations | Equivalent transformation |
| Fractional equations | Equivalent transformation |
| Quadratic equations | Quadratic formula (PQ) Quadratic formula (abc) |
| Biquadratic equations | Substitution |
| Cubic equations | Polynomial long division |
