having problem solving a limit!! 1. The problem statement, all variables and given/known data Solve the following limits algebraically. lim x->5 x^2 - 25 / √(2x+6) -4 2. Relevant equations 3. The attempt at a solution i've tried a different few ways. so by factoring the top i have (x+5)(x-5) so i get x=5 or x=-5, and while 5 is the limit, -5 on top with the square it will just render the negative sign useless. tried to multiply the bottom cognitive (x^2-25)(√(2x+6)+4)/(√(2x+6)-4)(√(2x+6)+4) = =(x^2-25)(√(2x+6)+4)/(√(2x+6))^2 - (4)^2 = =(x^2-25)(√(2x+6)+4)/2x+6-16= =(x^2-25)(√(2x+6)+4)/2x-10 i'm stuck here and i doubt this is even the proper route.
