Answer:

f(n) - g(n) = (4n + 3) - (3 {n}^{2}  + 2) \\  = 4n + 3 - 3 {n}^{2}  - 2 \\  =  \boxed{4n - 3 {n}^{2}  + 1}

<h3><u>(4n²-3n+1)</u> is the right answer.</h3>

Answer:

(4n + 3) - (3 {n}^{2}  + 2) \\  = 4n + 3 - 3 {n}^{2}   - 2 \\  =  - 3 {n }^{2}  + 4n + 1 \\ ( - 3 {n}^{2}   - 3n) - (1n + 1) \\  - 3n(n + 1) - 1(n + 1) \\ (n + 1)( - 3n - 1) \\ n =  - 1 \\  n=  \frac{1}{ - 3}
