$ \lim_{x \to -\frac{3}{2}} \frac{(4x^2 - 6x)(4x^2 + 6x + 9)}{\sqrt{2x - \sqrt{3}}} $
\(\frac{3\sqrt{14}}{2}\)
- First, factorize the quadratic expressions in the numerator if possible to simplify the expression.
- Substitute \(x = -\frac{3}{2}\) in the simplified equation and check the value of the denominator, as \(x\) approaches \(-\frac{3}{2}\), to determine the behavior of the function.
- If the function presents an indeterminate form like \( \frac{0}{0} \), apply L'Hôpital's Rule or algebraic manipulation to resolve the indeterminacy.
- Finally, evaluate the limit to find the exact value.
If
\[ A = \{ P(\alpha, \beta) \mid \text{the tangent drawn at P to the curve } y^3 - 3xy + 2 = 0 \text{ is a horizontal line} \} \]
and
\[ B = \{ Q(a, b) \mid \text{the tangent drawn at Q to the curve } y^3 - 3xy + 2 = 0 \text{ is a vertical line} \} \]
then \( n(A) + n(B) = \)
