i'm going to combine like termms and see where that gets me.
Problem:
Solution attempt:
upon distribution of coefficients,
If I didn't subtract as I did in step 1 I end up with,
This is where I am confronted with many mathematically valid yet counter productive steps as I try to solve for
combining like terms I have,
Answer in book:
notes: what gets me is the fact that I have two and
<sigh>...I got it...
differentiating both sides...
distributing coefficients...
combining like terms...
subtracting from both sides...
subtracting from both sides...
factoring out from right...
dividing both sides by ...
now for some rearrangement as well as multiplying both sides by ...
Thank you both
