Please help me solve and find the excluded values for this problem. Also please show me the work for this problem I want to learn! h(x)=x^2-9/x^2-4x+3

1. Reiny

same idea as before, factor first, then divide, restrict what you divided by
Again, I am putting in the brackets, they are extremely important here

h(x)=(x^2-9)/(x^2-4x+3)

= (x+3)(x-3)/(x-1)(x-3))
= (x+3)/(x-1) , x ≠ 3
