Find the Vertex

100

f(x) = (x - 3)² + 1

(3, 1)

200

f(x) = (x + 4)²

(-4, 0)

300

f(x) = x² - 7

(0, -7)

400

f(x) = x² + 6x + 5

(-3, -4)

500

f(x) = 3x² + 6x - 9

(-1, -12)

Convert to Standard Form

100

y = (x - 2)(x + 3)

y = x² + x - 6

200

y = 2(x - 4)(x - 7)

y = 2x² - 22x + 56

300

y = -3(x - 5)(x + 3)

y = -3x² + 6x + 45

400

y = (x - 4)² + 5

y = x² - 8x + 21

500

y = -(x + 5)² - 11

y = -x² - 10x - 36

Convert to Factored Form

100

y = x² - 5x + 4

y = (x - 1)(x - 4)

200

y = 2x² + 13x + 20

y = (2x + 5)(x + 4)

300

y = 7x² + 48x +36

y = (7x + 6)(x + 6)

400

y = x² - 12x + 36

y= (x - 6)²

500

y = x² - 49

y = (x - 7)(x + 7)

Find the Zeros by Factoring

100

y = (x + 4)(x - 5)

x = -4 & x = 5

200

y = (6x - 3)(x + 8) 

x = 1/2 (or 0.5)  &  x = -8

300

y = 2x² - 3x - 5

x = 5/2 (or 2.5)  & x = -1

400

y = 5x² + 19x + 12

x = -4/5 (or -0.8)  & x = -3

500

y = x² + 18x + 81

x = -9

Find the Zeros by Taking Square Roots

100

x² - 31 = 5

x = 6 & x = -6

200

4x² + 6 = 70

x = 4 & x = -4

300

(x +5)² - 64 = 0

x = 3 & x = -13

400

5(x - 2)² + 1 = 21

x = 4 & x = 0

500

(4x - 1)² - 3 = 6

x = 1 & x = -1/2 (or -0.5)
