- Factorisation - only works if the solutions are rational, so not always possible).
- Graph it - only works if solutions are real. Although this method WILL find irrational soultions, it may be difficult to relate answer to simple surd forms eg very few people could recognise 1.32288.. as sqrt(7)/2!. Also, it is difficult to read solutions off a graph to a high degree of precision.
- Numerical methods - only works if solutions are real. Can go to high precision but you still have the problem of relating an infinite decimal to a simple surd representation.
- Use quadratic equation - always provides a solution if you allow complex numbers.

What are some ways to solve an equation?
solve it
What are all the ways you can solve a quadratic equation?
First, write the equation in standard form, i.e., put zero on the right. Then, depending on the case, you may have the following options:Factor the polynomialComplete the squareUse the quadratic formula
What are different ways to solve a system of equation?
That depends on what type of equation it is because it could be quadratic, simultaneous, linear, straight line or even differential
Name four ways to solve a quadraic equation?
Four? Factoring Graphing Quadratic Equation Completing the Square There may be more, but there's at least four.
How do you find solutions to quadratic eqations?
There are several ways to solve such equations: (1) Write the equation in the form polynomial = 0, and solve the left part (where I wrote "polynomial"). (2) Completing the square. (3) Use the quadratic formula. Method (3) is by far the most flexible, but in special cases methods (1) and (2) are faster to solve.
