Week 14 Blog

Things i learned this week: when we solve rational expressions, we need to find their common denominator.

For example:

\frac{latex x^2$+2 over}{x^2 -x-6 over }

{x^2 -x-6 over }   can be factored into x^2-x-6=0


x=3, x=-2

if we found the common denominator,then we can factor it, that’s the way how we solved this kind of equation.
