lim_{x rightarrow -1} (x^2 - 7x + 8/ x - 5)^2

Question

anonymous · Answer

$$\lim_{x \rightarrow -1} (x^2 - 7x + 8/ x - 5)^2$$

myininaya · Answer

plug in -1 since the function is continuous at -1

anonymous · Answer

i tried that and i dont know what im doing wrong but my software wont accept the result

myininaya · Answer

$$\frac{(-1)^2-7(-1)+8}{(-1-5)^2}$$
is that right?

myininaya · Answer

or is the square on the whole thing?

anonymous · Answer

what happens to the exponent outside the paranthesis

myininaya · Answer

could you answer my question first?
is the square on the whole thing or just the bottom?

anonymous · Answer

the whole thing

myininaya · Answer

$$(\frac{(-1)^2-7(-1)+8}{(-1-5)})^2$$

myininaya · Answer

so perform what is inside first

myininaya · Answer

$$(\frac{1+7+8}{-6})^2=(\frac{16}{-6})^2=(\frac{-8}{3})^2=\frac{64}{9}$$
