Answer:

option B

Step-by-step explanation:

hope you meant - x²

You've choose factors of 35 which when added gives -2 and product gives -35. So i choose -7 and 5

[tex]-x^2 + 2 x + 35 = -1 (x^2 - 2x - 35)[/tex]

                    [tex]=-1 (x^2 - 7x + 5 x - 35)\\= -1 ( \ x(x - 7) + 5 (x - 7) \ )\\= - 1 (x+5)(x-7)[/tex]
