Aubree Cardenas · Answer 1

-13x^2 - 130x - 273 = 0

divide through by - 13:-

-13 (x^2 + 10x + 21) = 0

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

x = - 7 or - 3

Its D

Beautiful · Answer 2

-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
