3b because b^2-4= 1/b. So 2/1/b= 2b b+2b = 3b
The first step to solving this is to write 7x as a difference
x² + 9x - 2x - 18
next you need to factor out x from the expression
x × (x + 9) - 2x - 18
then you'll need to factor out -2 from the expression
x × (x + 9) - 2 (x + 9)
lastly,, you need to factor out x + 9 from the expression
(x + 9) × (x - 2)
this means that the correct answer to your question is (x + 9) × (x - 2).

Hi! took the quiz, it's associative properties
\[(7.556\times 10^9)-(3.8\times 10^6) \]
\[=(7.556\times 10^3)10^6-(3.8)10^6\]
\[=(7556-3.8)10^6\]
\[=(7552.2)\times 10^6\]
\[=7.5522\times10^3\times10^6\]
<span>\[=7.5522 \times10^9\]</span>
