For 1-3 solve the equation using the square root property

1. (m+1)^2 = -1

2. (p-1)^2 = 12

3. (t+5)^2 = -18

For 4 & 5, find the value of n such that the expression is a perfect square trinomial, then factor it.

4. X^2 -9X+n

5. Z^2 -2/5z +n

For 6-8, solve the equation by completing the square and applying the square root property

6. 3X^2 + 2X +1 = 0

7. W^2 + 4W = -13

8. b^2 + 7/2b = 2

For 9-11, write the function in the vertex form of a parabola and give the coordinates of the vertex, X-intercepts, y- intercepts and sketch a graph by hand.

9. P(x) = -5X^2 -10X -13

10. Z(x) = X^2 -6X +7

11. q(x) = -3X^2 -24X -54
