Differentiate Product
1. Stating the problem: Differentiate the function $y=(2x-1)(4x+3)$ with respect to $x$.
2. Use the product rule for differentiation: If $y = u \, v$, then $\frac{dy}{dx} = u'v + uv'$.
3. Identify $u=2x-1$ and $v=4x+3$.
4. Differentiate both functions individually:
$$u' = \frac{d}{dx}(2x-1) = 2$$
$$v' = \frac{d}{dx}(4x+3) = 4$$
5. Apply the product rule:
$$\frac{dy}{dx} = u'v + uv' = 2(4x+3) + (2x-1)4$$
6. Simplify each term:
$$2(4x+3) = 8x + 6$$
$$(2x-1)4 = 8x - 4$$
7. Add the terms:
$$8x + 6 + 8x - 4 = (8x + 8x) + (6 - 4) = 16x + 2$$
Final answer:
$$\frac{dy}{dx} = 16x + 2$$
