The simplified expression is:

[tex]g(x)-f(x) = x^2-6x-1[/tex]

Solution:

Given that the expression is:

[tex]g(x) - f(x) = (x^2-x+3)-(5x+4)[/tex]

We have to simplify the expression

The expression can be simplified by combining the like terms

Like terms are terms that have the same variables and powers. The coefficients do not need to match

From given,

[tex]g(x) - f(x) = (x^2-x+3)-(5x+4)\\\\Remove\ the\ paranthesis\ and\ solve\\\\g(x) - f(x) = x^2-x+3-5x-4\\\\Combine\ the\ like\ terms\\\\g(x)-f(x) = x^2-x-5x+3-4\\\\Add\ the\ like\ terms\\\\g(x)-f(x) = x^2 -6x + 3 - 4\\\\Add\ the\ constants\\\\g(x)-f(x) = x^2 -6x -1[/tex]

Thus the expression is simplified
