Answer:

<u>The correct answer is C. 9 -√ 105/ 2,  9 + √ 105/ 2</u>

Step-by-step explanation:

Let's find the solutions for the quadratic equation:

x² = 9x + 6

x² - 9x -6 = 0

Using the quadratic formula, we have:

x = [- (-9) +/- √ (-9)² - 4 * 1 * -6]/2 * 1

x = [ 9 +/- √ (81 + 24]/2

x = [ 9 +/- √ (105]/2

<u>x₁  =  [ 9 + √ (105]/2</u>

<u>x₂ =  [ 9 - √ (105]/2</u>

<u>The correct answer is C. 9 -√ 105/ 2,  9 + √ 105/ 2</u>
