## anonymous 5 years ago Multiply: [c+1/4][c+1/2] = Simplify answer??????

1. anonymous

I got c^2+3/4c+1/8????

2. anonymous

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

3. anonymous

thanks so much

4. anonymous

like heck you do!

5. anonymous

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

6. anonymous

$\frac{3}{4}\neq\frac{3}{4}\times 8$

7. anonymous

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

8. anonymous

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!

9. anonymous

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.

Oh ok gotcha, I see what you are saying

11. anonymous

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