Nice, EP !!!!!!!
Very nice, FMP !!!!!!
h-1 (5) means that
5 = ( 1 + y) / ( 2 - 2y)
5 ( 2 - 2y) = 1 + y simplify
10 - 10y = 1 + y
10 - 1 = 10y + y
9 = 11y
y = 9 / 11 = h-1 (5)
Here is a very similar problem that should help .....

Sorry, Ninchux.....!!!!!
You gotta' be fast around here....LOL!!!!

The sum of the roots = a + b = 9/2
The product of the roots = ab = 2/2 = 1
And note that
1/ ( a - 1) + 1 /( b - 1) =
b -1 + a - 1
_____________ =
(a - 1) ( b - 1)
a + b - 2
____________ =
ab - a - b + 1
( a + b) - 2
_______________ =
ab - (a + b) + 1
9/2 - 2
__________ =
1 - (9/2) + 1
5/2
_______ =
-5/2
-1
Note that x^2 + 6x -27 = ( x - 3) ( x + 9)
So the first term actually reduces to x + 9
This wil "cancel" with the denominator of the other term....so.....you are left with
3x
Good job !!!!!
See here
We have two obtuse triangles ABC and ACD
Both have bases of 1 and heights of 1 and 3 respectively
Total area = (1/2) (1) ( 1 + 3) = 2 units^2
100 in = 8 ft 4 inches = (8 + 1/3) ft per / min
As long as " a" is not equal to -1/2, the largest possible degree of f(x) + a* g(x) = 4
