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)

• 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)
