If I had to say anything to say when you click the button, I would've said, please finish this until the end which might take one day. Then do the quiz. Algebra is a type of algorithm that allows you to find a series of unknowns. If you spin around at the difficulty of this, DO NOT blame me. So here we go. You have been warned. Good luck!!!

Linear equations are the easiest of all. They do not involve any powers at all. Square roots maybe, but never powers. Linear equations are any equations that are written with a, b, c and so on which are real numbers, either positive or negative. x would be the variable. The basic principles are: if a = b, a - c = b - c, a + c = b + c and ac = bc. Graphs for this type of equations involve one straight line. For y = 2x + 1 as the line increases at y, it increases twice as fast as it increases at x, thus 2x.

Quadratic equations are quite a bit harder than their cousin, linear equations. They involve the power of two, cubing, and more advanced mathematics. It also relies on the quadratic equation = a2 + b = 0. The graph in this case does not involve a straight line, but a curved line. Demonstration is below.

This is the big daddy of the equation world. The macho men. The cubic equation uses not squares but cubes which means the number x itself x itself. It also can use the squares as well as the cubes. The graph doesn't involve a straight line or a curve but it involves two curves in the same graph.
