thank you guest. that was very helpful

to simplify is to make terms look simpler. For example, we could have 5x-2+27x-42-3x+10=24

Simplifying would give 29x-34=24

simplifying does not have to mean solve.

Sorry Guest

It would not make sense to have that. If there is, post it.

Please fix your latex. You can express functions as f(x)=y

Do you mean a repeating symbol like this? It means the numbers repeat. For example:

$\frac{1}{7}=0.\overline{142857}=0.142857142857142857142857...$

Your're Welcome!

It is not the same. Factoring helps us get the answer faster.

For example x^2+6x+7=0

Solving for x would be difficult using this form. But factoring we can get (x+6)(x+1)=0. We can easily solve for x which is -6,-1.
