Answer:


3x^2 - 4x + 15

Explanation:

We are simplifying the expression:


(5x^2 + 3) - (2x^2 + 4x - 12)

First, we can rewrite the expression without parentheses, remembering to distribute the negative to each subterm in the second term.


5x^2 + 3 - 2x^2 - 4x + 12

Next, we can group like terms.


(5x^2 - 2x^2) - 4x + (3 + 12)

Finally, these like terms can be combined.


\boxed{3x^2 - 4x + 15}
