$\large\mathcal\red{solution}$

Applying middle term method......

$3x {}^{2} - 7x + 2 \\ = 3x {}^{2} - 6x - x + 2 \\ = 3x(x - 2) - 1(x - 2) \\ = (x - 2)(3x - 1)$

Answer 2

Answer:

$3x {}^{2} - 7x + 2 \\ 3x {}^{2} - 6x - x + 2$

$3x(x - 2) - 1(x - 2) \\ (3x - </em><em>1</em><em>) \: and \: ( x - 2) \\ 3x - </em><em>1</em><em> = 0 \\ 3x = </em><em>1</em><em> \\ x = </em><em>1</em><em>\div 3 \\ \\ x - 2 \\ x = 2$
