Answer:
x³ + 4 x² + x - 6
Step-by-step explanation:
( x - 1 ) ( x + 2 ) ( x + 3 )
( x - 1 ) ( x + 2 ) = x² + 2 x - 1 x - 2 = x² + x - 2
( x² + x - 2 ) ( x + 3 ) = x³ + 3 x² + x² + 3 x - 2 x - 6 = x³ + 4 x² + x - 6

Let x = times in the pool
Let y = times in the basketball courts
42=3x+5y
x+y=12
Therefore y = 12-x
Subsitute for y
42 = 3x + 5(12-x)

Subtract 60
-18 = -2x
9 = x
