Simplify the rational expression state any restrictions on the variable
t^2+2t-24 / t^2-36

I got t-4 / t-6, but Im not sure of the restrictions whether its 6 or -6,6

• algebra -

t can not equal positive 6.

• algebra -

• algebra -

t also cannot be +6, since then t^2-36 = 0 ad the original fraction is not defined.

• algebra -

the answer choices only give =/6 or =/-6,6 so now confused
