<u>Here are your fill-ins:</u>
r = 1 is a zero, so (r-1) is a factor.
r = -1 is a zero, so (r+1) is a factor.
The remainders from synthetic division are 0 each time.
See the attachment for the synthetic division numbers.
_____
The reduced quadratic is ...
... x² -6x +13 = 0
Solving by completing the square, we have ...
... (x -3)² = -4
... x = 3 ± 2i
_____
The quadratic formula would tell you ...
... x = (-(-6) ± √((-6)² -4(1)(13)))/(2·1) = (6±√-16)/2 = 3±2i
Answer:
Step-by-step explanation:
If the projectile is hitting something on the ground, it has a height of 0. Sub in a 0 for the h and factor to solve for t:
Factor out a -16t to get
0 = -16t(t - 2.5) which means that either t = 0 or t = 2.5
I'd say it has to be t = 2.5, don't you? ; )
