Hey can you me posted picture of question : )

The roots are:


Explanation: 
First we would need to put the equation in standard form which is as follows:
ax² + bx + c = 0
This can be done as follows:
9x² + 6x + 1 = 8
Subtract 8 from both sides and combine like terms to reach the following:
9x² + 6x - 7 = 0
By comparison:
a = 9
b = 6
c = -7

Now, to get the roots, we would need to use the quadratic formula attached in the images.

By substitution, we would find that:
either x = 

or x =

Hope this helps :)

The answer to your question is b’(16,14)
