Convert Forms of Quadratic Equations

Identify the form of the equation

• Standard Form

• Factored Form

• Vertex Form

Select all of the equations that are represented by the graph below.

Convert the function to standard form:

f(x) = -2(x + 9)(x - 3)

• f(x) = -2x² - 12x + 54

• f(x) = x² + 6x - 27

• f(x) = 2x² + 12x - 54

• f(x) = -x² - 6x + 27

Convert to standard form:

y = (m - 9)(m + 5)

• y = m² - 4m - 45

• y = m² - 14m - 45

• y = m² + 4m - 45

• y = m² + 14m - 45

Convert the function to standard form:

y = (x + 7)(x + 5)

• y = 2x² + 35x + 12

• y = x² + 35x + 12

• y = 2x² + 12x + 35

• y = x² + 12x + 35

Convert the function to standard form:

f(x) = -3(x + 5)(x - 4)

• f(x) = 3x² + 3x - 60

• f(x) = -3x² - 3x + 60

• f(x) = x² + x - 20

• f(x) = -x² - x + 20
