$= - x (x - 2)$ $=-x(x-2)$

$5 x (x + 4) - 6 x (x + 3) = 5 x^{2} + 20 x - 6 x^{2} - 18 x$ $5x(x+4)-6x(x+3)=5x^2+20x-6x^2-18x$

$= 5 x^{2} - 6 x^{2} + 20 x - 18 x$ $=5x^2-6x^2+20x-18x$

$(5 - 6) x^{2} + (20 - 18) x$ $(5-6)x^2+(20-18)x$

$- 1 x^{2} + 2 x$ $-1x^2+2x$

$(- x + 2) x$ $(-x+2)x$

$= - x (x - 2)$ $=-x(x-2)$
