Which shows the unsimplified solution for x^2 + 8x + 6 = 0?

irinina [24]

<u /> $x^{2} + 8x + 6 = 0 \\x = \frac{-(8) +/- \sqrt{(8)^{2} - 4(1)(6)}}{2(1)} \\x = \frac{-8 +/- \sqrt{64 - 24}}{2} \\x = \frac{-8 +/- \sqrt{40}}{2} \\x = \frac{-8 +/- 2\sqrt{10}}{2} \\x = -4 +/- \sqrt{10}$
$x = -4 + \sqrt{10}$ $x = -4 - \sqrt{10}$

It is equal to D.
