What is \( E+F ? \quad E: 6 c^{2}-2 c-1 \quad F:-4 c^{2}+7 c+5 \)

To find \( E + F \), we need to combine the polynomials \( E \) and \( F \). The expressions are: - \( E = 6c^2 - 2c - 1 \) - \( F = -4c^2 + 7c + 5 \) Now, let's add them together: \[ E + F = (6c^2 - 2c - 1) + (-4c^2 + 7c + 5) \] Combine like terms: 1. Combine the \( c^2 \) terms: \( 6c^2 - 4c^2 = 2c^2 \) 2. Combine the \( c \) terms: \( -2c + 7c = 5c \) 3. Combine the constant terms: \( -1 + 5 = 4 \) Putting it all together, we get: \[ E + F = 2c^2 + 5c + 4 \] So, \( E + F = 2c^2 + 5c + 4 \).
