Question

Splitting middle term​

Answer 1

Answer:

3( x² + 20x - 96 ) =0

x² + 20x - 96 = 0

x² + 12x + 8x - 96

x( x + 12 ) -8 ( x+ 12)

( x -8 )

( x+12)

therefore either 8 or - 12

Answer 2

$3x {}^{2} + 60x - 288$

$3( {x}^{2} + 20x - 96)$

$3( {x}^{2} + 24x - 4x - 96)$

$3(x(x + 24) - 4(x + 24))$

$3(x + 24)(x - 4)$
