What are the exact solutions of x^2 − 3x − 7 = 0?

Given:

The given equation is

We need to determine the exact solutions of the equation.

Exact solution:

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

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

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

Thus, the exact solutions of the given equation is

Hence, Option A is the correct answer.

1/4 and 8/3 because:

the reciprocal if 4 is 1/4 because 4 is used as 4/1 and the opposite of that is 1/4. the opposite of 3/8 is 8/3 so that is the answer.
