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

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

Put 2x² = 3x - 4 in standard form

• 2x² + 3x - 4 = 0

• 2x² - 3x + 4 = 0

• 2x² - 3x - 4 = 0

• 2x² + 3x + 4 = 0
