$= 6 x^{2} - 287 x + 3$ $=color(blue)(6x^2) color(green)(−287x)+3$

$4 x^{2} - 20 x + 32 x + 1 + 2 x^{2} - 25 x - 274 x + 2$ $4x^2−20x+32x+1+2x^2−25x−274x+2$

Grouping all the coefficients of $x^{2}$ $x^2$ , $x$ $x$ and the constant terms together.

$= 4 x^{2} + 2 x^{2} - 20 x + 32 x - 25 x - 274 x + 2 + 1$ $=color(blue)(4x^2+2x^2) − color(green)(20x+32x−25x−274x)+2+1$

$= 6 x^{2} - 287 x + 3$ $=color(blue)(6x^2) color(green)(−287x)+3$
