Six months ago, I would have just laughed at you for showing me these
For jenny , primarily: here are a few samples of what we're working on as we gear up for the final exam in algebra.
((5k^2-4k-1)/(5k^2+12k+7))/((25k^2-1)/(5k^2+2k-7))
Solution: ((k-1)(k-1))/((k+1)(5k-1))
Or this prime cut of of math meat:
((1)/(x-2)+(3)/(x+6))/((3)/(x+6)-(2)/(x-4))
Solution: ((4x)(x-4))/((x-2)(x-24))
And I still have two flippin' quarters of ( Read more... )
