Evaluate the following expression using the given values:

Find \(-3a^2 - b^3 + 3c^2 - 2b^3\) if \(a = 2\), \(b = -1\), and \(c = 3\).

-3(2^2) - 3(-1) + 3(3^2) - 2(-1^3) -3(4) - 3(-1) + 3(9) - 2(-1) -12 + 3 + 27 + 2 -9 + 27 + 2 18 + 2 20

After substituting the values a = 2 , b = − 1 , and c = 3 into the expression − 3 a 2 − b 3 + 3 c 2 − 2 b 3 , we find that the result is 18 .
