To learn how to get started, try studying some online lessons on solving radical equations and factoring quadratics.

Once you've learned the basic terms and techniques, you can attempt the exercises. For the first one, a good start would be to subtract the x to the right-hand side, and then square both sides, keeping in mind that (8 - x)^2 means (8 - x)(8 - x).

For the second one, I'm not sure if they want you to square first, and then solve by factoring, or else rearrange as follows:

. . . . .$\displaystyle \left(\sqrt{x}\right)^2\, -\, 1\sqrt{x}\, -\, 6\, =\, 0$
