• -1 and 3

• -1.2 and 3.2

• -4

• -1.5 and 3.5

Which statement about f(x)= -x²-5x+24 is true?

• The zeros are 8 and 3, because f(x)= -(x-8)(x-3)

• The zeros are 8 and -3, because f(x)= -(x-8)(x+3)

• The zeros are -8 and 3, because f(x)= -(x+8)(x-3)

• The zeros are -8 and -3, because f(x)= -(x+8)(x+3)
