Factor to find the zeros of the function defined by the quadratic expression. −13x^2 − 130x − 273 a) x = 7 or x = 3 b) x = 7 or x = −3 c) x = −7 or x = 3 d) x = −7 or x = −3

−13x^2 − 130x − 273

= -13(x^2 + 10x + 21)

= - 13(x + 3)(x + 7)

- 13(x + 3)(x + 7) = 0

x + 3 = 0; x = -3

x + 7 = 0; x = -7

Answer

D)x = −7 or x = −3
