1. **State the problem:** Find the discriminant of the quadratic equation and determine how many real solutions it has.
The equation is given as:
$$1 = -5t^2 - 7t$$
2. **Rewrite the equation in standard form:**
Bring all terms to one side:
$$-5t^2 - 7t - 1 = 0$$
3. **Identify coefficients:**
For a quadratic equation $$at^2 + bt + c = 0$$, here:
$$a = -5, \quad b = -7, \quad c = -1$$
4. **Formula for the discriminant:**
$$\Delta = b^2 - 4ac$$
5. **Calculate the discriminant:**
$$\Delta = (-7)^2 - 4 \times (-5) \times (-1) = 49 - 20 = 29$$
6. **Interpret the discriminant:**
- If $$\Delta > 0$$, there are two distinct real solutions.
- If $$\Delta = 0$$, there is exactly one real solution.
- If $$\Delta < 0$$, there are no real solutions.
Since $$\Delta = 29 > 0$$, the equation has two real solutions.
**Final answer:** The equation has two real solutions.
