Standard form: $y = 5 x^{2} - 3 x - 2$ $y=5x^2-3x-2$

Explanation:

Standard form for a quadratic is
$XXXX$ $color(white)("XXXX")$ $y = a x^{2} + b x + c$ $y =ax^2+bx+c$ for constants $a, b, and c$ $a, b, and c$

Multiplying $(x - 1) (5 x + 2)$ $(color(red)(x)color(blue)(-1))(5x+2)$
as $(x) (5 x + 2) - 1 (5 x + 2)$ $color(red)((x))(5x+2)color(blue)( - 1)(5x+2)$
$= 5 x^{2} + 2 x - 5 x - 2$ $= color(red)(5x^2+2x)color(blue)( - 5x -2)$
$= 5 x^{2} - 3 x - 2$ $=5x^2-3x-2$
allows us to rewrite the equation in this standard form.
