Question

(12x² - 8x) : (+2x) =​

Answer 1

$\frac{d}{dx}\left(\frac{\left(12x^2-8x\right)}{\left(2x\right)}\right)\\\\=\frac{d}{dx}\left(2\left(3x-2\right)\right)\\\\=2\frac{d}{dx}\left(3x-2\right)\\\\=2\left(\frac{d}{dx}\left(3x\right)-\frac{d}{dx}\left(2\right)\right)\\\\=2\left(3-0\right)\\\\=6$
