Answer:
(x -y -1)(x +y)
Step-by-step explanation:
The expression can be factored by grouping.
x^2 -y^2 -x -y = (x^2 -y^2) -(x +y)
= (x -y)(x +y) -1(x +y)
= (x -y -1)(x +y)
_____
It is useful to know that a difference of squares is factored as ...
a^2 -b^2 = (a -b)(a +b)
I hope this helps, let me know if it doesn't make sense
Given parameters:
Distance traveled = 1778miles
Average speed = 61.7 miles per hour
Unknown:
Time taken for the travel = ?
Speed is a physical quantity. It is the rate of change of distance with time.
It can be mathematically expressed as;
Speed =
The unknown here is the time taken;
Substitute the parameters and solve for it;
61.7 =
time taken = = 28.8hrs
The time taken is 28.8hrs
