Answer:

(You only need to give one solution)
Step-by-step explanation:
We have the following equation

First, we need to foil out the parenthesis

Now we can combine the like terms

Now, we need to factor this equation.
To factor this, we need to find a set of numbers that add together to get -3 and multiply to give us -4.
The pair of numbers that would do this would be 1 and -4.
This means that our factored form would be

As the first binomial is a difference of squares, it can be factored futher into

Now, we can get our solutions.
The first binomial will produce two complex (Not real) solutions.


So our solutions to this equation are

Answer:
33.6 seconds
Step-by-step explanation:
if he begins at 136 feet and wants to go to 42 feet, the distance is 94 feet
d = 94
r = 2.8
d = rt; solving this formula for 't':
t = d/r
t = 94/2.8
t = 33.6 seconds
