Rewriting Quadratic Forms

What is the axis of symmetry? y = (x + 9)² + 1

• x = 9

• x = -9

• x = 1

• x = -1

Convert to Vertex Form: f(x) = x² +8x +14

• f(x) = (x - 4)² + 2

• f(x) = (x - 4)² - 2

• f(x) = (x + 4)² + 2

• f(x) = (x + 4)² - 2

Convert to standard form: f(x) = x2+3x-18

• (x-6)(x+3)

• (x+6)(x+3)

• (x+6)(x-3)

• (x-6)(x-3)

Convert to Standard Form: f(x) = (x+7)(x-3)

• f(x) = x² +10x +21

• f(x) = x² -10x -21

• f(x) = x² +4x -21

• f(x) = x² +4x +21

Convert to Factored Form:

x² - 10x + 24

• (x - 6)(x - 4)

• (x + 6)(x + 4)

• (x - 12)(x + 2)

• (x - 8)(x - 3)

Convert to Factored Form:

3a² + 4a + 1

• (7a-10)(a-8)

• Not factorable

• (3a+1)(a+1)

• (3a-1)(a-1)

Convert to Factored Form:

(hint: use slide n' divide)

4x²-16x-9

• (2x-9)(2x+1)

• (2x+9)(2x-1)

• (4x-1)(x+9)

• (x+1)(4x-9)
