See a solution process below..

Recall the standard form formula is;

$Ax + By = c$

Where;

$A, B and C$ are respective coefficients..

$y = (x - 12)(3x + 2)(7x - 4)$

Firstly, removing the brackets..

$y = 21x³ - 283x - 168 - 12x² + 136x + 96$

$y = 21x³ - 12x² - 283x + 136x - 168 + 96$

$y = 21x³ - 12x² - 147x - 72$

Rearranging the equation..

$21x³ - 12x² - 147x - y = 72$

What is the standard form of y= (x-12)(3x+2)(7x-4) y= (x-12)(3x+2)(7x-4)?
