Question

Is it possible to simplify this any further? ( x - 3 ) ( x - 4 ) ( x + 6 )

Answer 1

Answer:

x³ -x²-30x+72

Step-by-step explanation:

→ ( x - 3 ) ( x - 4 ) ( x + 6 )

[ expand and open brackets ]

→ ( x² -4x -3x + 12 ) ( x + 6 )

[ simplify ]

→ ( x² -7x + 12 ) ( x + 6 )

[ expand ]

→ x³ +6x² -7x²  - 42x + 12x + 72

[ simplify/ final answer ]

→ x³ -x² -30x +72

Answer 2

$(x-3)(x-4) (x + 6)$

[expand and open brackets ]

$→(x² -4x -3x + 12 ) ( x + 6)$

[simplify]

$→(x² -7x + 12) (x+6)$

[expand]

$→x³ +6x² -7x² - 42x + 12x + 72$

[simplify/final answer ]

$→x³ -x² -30x +72$
