$6 x^{2} + 8 x - 30$ $6x^2+8x-30$
Factor out 2
$2 (3 x^{2} + 4 x - 15)$ $2(3x^2+4x-15)$

$(3 x - 5) (2 x + 6)$ $(3x -5)(2x +6)$

Takes a little bit of experimentation sometimes.

$(3 x - 5) (2 x + 6) = 6 x^{2} - 10 x + 18 x - 30$ $(3x -5)(2x +6) =6x^2 -10x +18x -30$

$= 6 x^{2} + 8 x - 30$ $= 6x^2 +8x-30$
