Find the zeros using the graph.
Solve using square roots. Leave your answer in simplest radical form if necessary. x2 + 5 = 17
4x2 + 25 = 73
x2 ­ 14 = ­14
(x ­ 1)2 = 0
(x + 2)2 = 64
19 = 30 ­ 5x2

Solve the equation by completing the square. Also, use completing the square to put the function in vertex form and state the vertex.
a) x2 + 6x ­ 40 = 0
b) x2 + 2x + 5 = 4
c) 2x2 ­ 4x = 10
Solve using any method. Leave your answer in simplest radical form if necessary.
x2 ­ 121 = 0
x2 ­ 6x = 10
x2 ­ 5x = ­3

Solve using any method. Leave your answer in simplest radical form if necessary.
x2 ­ 7x + 12 = 0
x2 + 6x + 1 = 0
­2x2 + 3x + 7 = 0
Solve the system using any method.
a) y = x2 ­ 4x ­ 2
b) y = x2 ­ 5
y = ­4x + 2
y = ­x + 7
