Answer:


3{x}^(2) + x + 4

Explanation:

Assuming the polynomials are


f(x) = 2 {x}^(2) + 3x - 5

and


g(x) = 5 {x}^(2) + 4x - 1

When f(x) is subtracted from g(x), we get;


g(x) - f(x) = 5 {x}^(2) - 2 {x}^(2) + 4x - 3x - 1 - - 5

We perform the subtracttion to get:


g(x) - f(x) = 3{x}^(2) + x + 4

Therefore the correct answer is


3{x}^(2) + x + 4
