Hello! Thank you for your question! I would be happy to help!

So here is what you would get if you use the quadratic formula:

x = 1 +- √253 / 14

x ≈ 1.20756955, -1.06471240
The quadratic formula that can be used to correctly solve 7x^2 = 9 + x for 'x' is:
[tex]x = \frac{1 + \sqrt{253}}{14}[/tex]
OR
x ≈ 1.20756955, -1.06471240
