Which of the following represents the factors of the expression x² - 3x - 40 ?

A.) (x - 8)(x + 5)

B.) (x - 7)(x + 4)

C.) (x + 10)(x - 4)

D.) (x + 6)(x - 9)

A.) (x - 8)(x + 5)

B.) (x - 7)(x + 4)

C.) (x + 10)(x - 4)

D.) (x + 6)(x - 9)

Factor the quadratic expression into two binomials.

The first terms of the two binomials are factors of x²......x and x

The second terms of the two binomials will multiply to get the constant term, -40, and add to get the middle coefficient, -3

x² - 3x - 40

=
