If a = 3 and b = -2, what is 2a^2 + 3b?

Explanation:
Substituting the given values into the expression and following the order of operations is what to do. Compute a^2 first: with a = 3, a^2 = 9. Then 2a^2 becomes 18. For the b term, 3b with b = -2 equals -6. Adding them together gives 18 + (-6) = 12. The negative sign from b reduces the total, showing how a negative multiplier affects the sum. So the value is 12.
