Completing the square

1)c^2-7c= -12

2)x^2-2x-8= 0

Incomplete Quadratic Equations

1) 2x^2-2 = 16

Any advice will be appreciated!

c^2-7c= -12

What is 1/2 of -7? Square that, and add to both sides.

x^2-2x-8= 0

What is 1/2 of -2? square that, and add to both sides

A cylinder has a radius of 5 in. If the volume of the cylinder is 250* pi in. ^3, what is the height of the cylinder

[Hint: The volume of a cylinder is given by V=pi * r&2 *h

Remember that pi = 3.14
