$(x -8)( x+3)$

In the $Ax^2 + Bx + C$ form of the equation the C is negative which means it must have one negative factor and one positive factor.

The B is negative which means that the negative factor is five greater than the positive factor.

$8 xx 3 = 24$ $color(white)(...) andcolor(white)(...)$ $8-3 = 5$

so the factors that work for 24 are -8 and+ 3

$( x-8)(x+3) = 0$

The factors are $(x-8)$ and $(x+3)$
