I just found this in a math book, not part of the assignment, and I'd like to know how 3x+7/x+7 doesn't equal 2x.
-A friend in fremont
3x+7/x+7 getting a common denominator of "x"
[ 3x^2 + 7 + 7x ] / x
One of our regulars, hectictar, pointed out to me that this might be :
(3 x + 7) / (x + 7) if so, we have
x + 7 [ 3x + 7 ]
3x + 21 ]
The result is 3 + [ -14 / ( x + 7) ]
Thanks , hectictar !!!!!
