Step-by-step explanation:

You do this the same way you would if i were a variable.

What are the exact solutions of x^2 − 3x − 7 = 0?
bulgar [2K]

<u>Given</u>:

The given equation is x^{2} -3x-7=0

We need to determine the exact solutions of the equation.

<u>Exact solution:</u>

The exact solution of the equation can be determined by solving the equation using quadratic formula,

x=\frac{-b \pm \sqrt{b^2-4ac}}{2a}

From the equation the values are a = 1, b = -3 and c = -7

Thus, substituting these values in the equation, we get;

x=\frac{-(-3) \pm \sqrt{3^2-4(1)(-7)}}{2(1)}

x=\frac{3 \pm \sqrt{9+28}}{2}

x=\frac{3 \pm \sqrt{37}}{2}

Thus, the exact solutions of the given equation is x=\frac{3 \pm \sqrt{37}}{2}

Hence, Option A is the correct answer.
