Help with number 50 please. Thanks.
Blizzard [7]

Answer:

d = 7 + 3\sqrt{3} and

d = 7 - 3\sqrt{3}

Step-by-step explanation:

To solve the equation, d^2 - 14d - 22 = 0, using the quadratic formula,

Recall: quadratic formula = \frac{-b ± \sqrt{b^2 - 4ac}}{2a}

Where,

a = 1

b = -14

c = 22

Plug in your values into the formula and solve:

\frac{-(-14) ± \sqrt{(-14)^2 - 4(1)(22)}}{2(1)}

\frac{14 ± \sqrt{196 - 88}}{2}

\frac{14 ± \sqrt{108}}{2}

d = \frac{14 + \sqrt{108}}{2}

d = \frac{14 + 6\sqrt{3}}{2}

d = (\frac{2(7 + 3\sqrt{3})}{2}

d = 7 + 3\sqrt{3}

And

d = \frac{14 - \sqrt{108}}{2}

d = \frac{14 - 6\sqrt{3}}{2}

d = (\frac{2(7 - 3\sqrt{3})}{2}

d = 7 - 3\sqrt{3}
