Use DOTS to factor the following polynomial, and then determine the solutions:
 $y=x^{2\ }-36$  

• x=6

• x=6, x=-6

• x=18, x=-18

• There are no solutions

To solve by completing the square, what needs to be moved in this equation?
x² = 9 - 4x

• the -4x

• the 9

• the x²

• none of these

In completing the square, when do you use the plus or minus symbol?

±

• After taking the square root of both sides

• After adding the square to both sides

• After taking half of b

• After setting the equation equal to zero

Solve the following equation for x:
