Addison Perez · Answer 1

6d² + 5d = 1

6 (-1) ² + 5 (-1) = 1

(6 * 1) + (-5) = 1

6 - 5 = 1

1 = 1

So d equals - 1

Alena Buckley · Answer 2

d = - 1 and 1/6

6d² + 5d - 1 = 0

6d² + 6d - 1d - 1 = 0

6d (d+1) - 1 (d+1) = 0

(6d - 1) (d+1) = 0

d+1 = 0

d = - 1

and d also is

6d - 1 = 0

6d = 1

d = 1/6
