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)=o

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.
