Is it possible to simplify this any further?

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

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

i believe your answer is 99.7% of 7-year-old children are between 46.6 inches and 49.5 inches tall.
