Please use the ^ sign for powers. As you have it written, the first one means

w times 2.

But anyway, for the first one. Notice the difference of two squares?.

. Now, can you factor using the proper form?. (x+y)(x-y). - February 28th 2008, 04:55 PMquarks

Take the square root of both sides.

For the other one, you can factor it.

And from there, it's easy to solve. - February 28th 2008, 05:26 PMtopsquark
