Louise wants to factorize completely the given polynomial 
Grouping first, second terms together and third, fourth terms together
=
Taking 
common from first and second terms of the given expression and taking 5 common from the third and fourth terms.
=
Taking (x+3) common from the given expression,
=
is the completely factored form.
For this we almost have the following equation:
We must match the equation to zero:
From here, we clear the value of t.
We have then:
We discard the negative root because we are looking for time:
Answer:
it will take him to reach the ground about:
seconds
The negative externalities must be present.
Answer:
15 divided by 4 = 3 3/4
Step-by-step explanation:
