1) Solve for the variable:
c%28c-1%29%28c%2B13%29+=+0 Apply the zero products principle.
c+=+0 and/or c-1+=+0 and/or c%2B13+=+0
Solutions are:
c = 0
c = 1
c = -13
2) Five times the square root of a number is 15, find the number:
Let n = the number.
5sqrt%28n%29+=+15 Divide both sides by 5.
sqrt%28n%29+=+3 Square both sides.
n+=+9
