$\frac{1}{\sqrt{-\left(x^2-6x-16\right)}}$
Learn how to solve limits by direct substitution problems step by step online. Rationalize the denominator 1/((16+6x-x^2)^1/2). Use the complete the square method to factor the trinomial of the form ax^2+bx+c. Take common factor a (-1) to all terms. Add and subtract \displaystyle\left(\frac{b}{2a}\right)^2. Factor the perfect square trinomial x^2+-6xx+9. Subtract the values -16 and -9.
