$y = (5 x + 1) \cdot (x - 2)$ $y=(5x+1)*(x-2)$

$y = 5 x^{2} - 9 x - 2$ $y=5x^2-9x-2$

$= 5 x^{2} + x - 10 x - 2$ $=5x^2+x-10x-2$

$= x \cdot (5 x + 1) - 2 \cdot (5 x + 1)$ $=x*(5x+1)-2*(5x+1)$

= $(5 x + 1) \cdot (x - 2)$ $(5x+1)*(x-2)$

Is it possible to factor y=5x2−9x−2y=5x^2-9x-2 ? If so, what are the factors?
