    \[(c+\frac{1}{4})(x+\frac{1}{2})=c^2+\frac{1}{2}c+\frac{1}{4}c+\frac{1}{8}\] \[=c^2+\frac{3}{4}c+\frac{1}{8}\]

    if you multiply by 8 you get something 8 times as large!

    \[\frac{3}{4}\neq\frac{3}{4}\times 8\]

    I think the way you wrote it at first in fraction form is the way they want it

    if you are solving an equation you can multiply both sides by 8. or whatever. but if you just have an expression you cannot multiply by 8!

    it is not a matter of 'fraction form' take the expression \[x+3\] multiply it by 8 you get \[8x+24\] which is not the same at all.

    whew. so don't do it! unless of course you are solving an equation and multiply both sides by something.
