The correct question is; x² + 2x - 24
The other factor of <em>x² </em><em>+</em><em> </em><em>2x </em><em>-</em><em> 24</em> asides (x+6) is; (x-4)
The expression given can be factorised as follows;
Consequently, the other factor of the expression is (x-4).

Answer:
Step-by-step explanation:
To find the time at which both balls are at the same height, set the equations equal to each other then solve for t.
h = -16t^2 + 56t
h = -16t^2 + 156t - 248
-16t^2 + 56t = -16t^2 + 156t - 248
You can cancel out the -16t^2's to get
56t = 156t - 248
=> 0 = 100t - 248
=> 248 = 100t
=> 2.48 = t
Using this time value, plug into either equation to find the height.
h = 16(2.48)^2 + 56(2.48)
Final answer:
h = 40.4736
