Converting Between Quadratic Forms

• y = (x+8)(x+6)

• y = (x+8)(x-6)

• y = (x-6)(x-8)

• y = (x-8)(x+6)

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:

f(x) = x²+3x-18

• f(x)=(x-6)(x+3)

• f(x)=(x+6)(x+3)

• f(x)=(x+6)(x-3)

• f(x)=(x-6)(x-3)

Convert to standard form: y = 5(x+9)² -17

• y = 5x² + 90x +388

• y = 5x² - 90x +388

• y = 5x² - 90x - 388

• y = -5x² + 90x +388

Convert to Factored Form:

y=3a² + 4a + 1

• y=(7a-10)(a-8)

• Not factorable

• y=(3a+1)(a+1)

• y=(3a-1)(a-1)

Which of the following shows
f(x) = x² - 8x + 1
written in vertex form?

• f(x) = (x - 4)² - 15

• f(x) = (x - 4)² + 17

• f(x) = (x - 4)² - 17

• f(x) = (x - 4)² + 65

• y = (x+8)(x+6)

• y = (x+8)(x-6)

• y = (x-6)(x-8)

• y = (x-8)(x+6)

• y = (3x - 21)(x + 2)

• y = 3(x - 7)(x + 2)

• y = (3x - 15)(x - 42)

• y = 3(x + 7)(x - 2)

Convert to Intercept form:

f(x) = x²+3x-18

• (x-6)(x+3)

• (x+6)(x+3)

• (x+6)(x-3)

• (x-6)(x-3)

Convert to Factored/Intercept Form

x² + 5x - 24

• (x - 8)(x + 3)

• (x + 8)(x - 3)

• (x + 6)(x - 4)

• (x + 12)(x - 2)
