1. ## need help with 3 algebra problems

Simplify

m-2/m^2-7m+10 + m+2/m^2-4m-5

Expand and simplify
(-3m^2+5m-3)+(m^2-6m+1)-(-3m^2-2m-4)

Expand and simplify
(3x+6)(x+3)^2-(3x-1)(2x+a)^2

Expand and simplify
(3x+6)(x+3)^2-(3x-1)(2x+a)^2
$\displaystyle \frac{m-2}{m^2-7m+10}+\frac{m+2}{m^2-4m-5}=\frac{m-2}{(m-2)(m-5)}+\frac{m+2}{(m+1)(m-5)}$

Can you take it from there?

Others problems are not hard, try it!
