Question
In Exercises $37-54,$ find the limit (if it exists).$$\lim _{x \rightarrow(-1 / 2)^{+}} \frac{6 x^{2}+x-1}{4 x^{2}-4 x-3}$$
Step 1
We can factorize the denominator as $(2x+1)(2x-3)$, but the numerator cannot be factorized. So, the function becomes: $$ f(x) = \frac{6x^2+x-1}{(2x+1)(2x-3)} $$ Show more…
