Question

evaluate the following expression using the values given: -a2 - 3b3 + c2 + 2b3 - c2 if a = 3, b = 2, and c = -3

Answer 1

\[-a ^{2}-3b ^{3}+c ^{2}-2b ^{3}-c ^{2}\]

Answer 2

is that the equation?

Answer 3

yes

Answer 4

\[-(3)^2 -3(2)^3 + (-3)^2 - 2(2)^3 - (-3)^2\]
-9-24+9-16-9
-49

Answer 5

thanx😊

Answer 6

I would simplify the expression first and then substitute:
\(\large -a^2 - 3b^3 + c^2 + 2b^3 - c^2 = -a^2 - b^3\)
Put a = 3 and b = 2
\(\large -3^2 - 2^3 = -9 - 8 = -17\)
