How The Hell Do You Solve This!?
March 16th, 2010------ - ------ = 72
6.........3
I keep trying to solve it but I don't get it right.
The dots between the 6 and the 3 don't mean anything I just used that to separate the two.
so (5q^2)/6 - q^2/3 = (5q^2)/6 - (2q^2)/6
now that there is a common denominator, you can simplify.
(5q^2 - 2q^2) / 6 = (3q^2) / 6
3/6 = 1/2
so q^2 / 2
now solve for q
q^2/2 = 72
multiply by 2
q^2 = 72*2
q = sqrt(72 *2)
5q^2. 2* q^2
------ - ------ = 72
6............ 2* 3
5q^2. 2 q^2
------ - ------ = 72
6.............. 6
5q^2. - 2* q^2
---------------------- = 72
6.
3q^2 = 72*6
q^2 =(452/3)= 144
q = + or - square root of (144)
q=+ - (12)
------ - ------ = 72
6.........3
3 (5q^2) - 6 (q^2) = 72

15q^2 - 6q^2= 72
__________
18
15q^2 - 6q^2= 1296
9q^2= 1296
q^2= 144
q= 12
------ - ------ = 72
6.........3
5q^2.... 2q^2
------ - ------ = 72
6.........6
3q^2= 72(6)
q^2 = 144
q = +-12
------ - ------ = 72
6.........3
5q^2.... 2q^2
------ - ------ = 72
6.........6
=> 7q^2 = 6(72)
