Solve by factoring or finding square roots. 6x^2+9=-55x

(6x + 1) (x + 9)

Step-by-step explanation:

6x^2 + 9 = - 55x

6x^2 + 55x + 9 = 0

55 is a pretty big number compared to either 6 or 9. Not only that, but 6*9 = 54.

So the answer is going to depend on multiply 6x together with 9

(6x + __) (x + 9)

Now what goes were the underline is?

You have 54x. You need but 1 more to get 55x. So a one must go where the underline is.

(6x + 1) (x + 9) Answer
