To perform the operation, we need to remove the parentheses and combine like terms.
The given expression is: 3x^2 + 4x + 3 - (-4x^2 - 3)
Removing the parentheses, we get: 3x^2 + 4x + 3 + 4x^2 + 3
Combining like terms, we have: (3x^2 + 4x^2) + 4x + (3 + 3)
Simplifying further: 7x^2 + 4x + 6
perform the indicated operation by removing the parentheses and combining like terms (3x^2+4x+3-(-4x^2-3)
