To simplify the expression \( c = -\sqrt{30} \times -\sqrt{30} \), you can follow these steps:
1. Recognize that multiplying two negative numbers results in a positive number:
\[
-\sqrt{30} \times -\sqrt{30} = \sqrt{30} \times \sqrt{30}
\]
2. When you multiply square roots, you can combine them under a single square root:
\[
\sqrt{30} \times \sqrt{30} = \sqrt{30 \times 30} = \sqrt{900}
\]
3. The square root of 900 is 30:
\[
\sqrt{900} = 30
\]
Therefore, \( c = 30 \).
