Math Problem Statement

Given that f, of, x, equals, x, squared, minus, 11, x, plus, 30f(x)=x 2 −11x+30 and g, of, x, equals, x, minus, 5g(x)=x−5, find left parenthesis, f, minus, g, right parenthesis, left parenthesis, x, right parenthesis(f−g)(x) and express the result as a polynomial in simplest form. '

Solution

We are asked to find (fg)(x)(f - g)(x), which means we need to subtract the function g(x)g(x) from f(x)f(x).

Given: f(x)=x211x+30f(x) = x^2 - 11x + 30 g(x)=x5g(x) = x - 5

Now, let's compute (fg)(x)(f - g)(x): (fg)(x)=f(x)g(x)(f - g)(x) = f(x) - g(x) Substitute f(x)f(x) and g(x)g(x): (fg)(x)=(x211x+30)(x5)(f - g)(x) = (x^2 - 11x + 30) - (x - 5)

Distribute the negative sign: (fg)(x)=x211x+30x+5(f - g)(x) = x^2 - 11x + 30 - x + 5

Now, combine like terms: (fg)(x)=x212x+35(f - g)(x) = x^2 - 12x + 35

Thus, the result is: (fg)(x)=x212x+35(f - g)(x) = x^2 - 12x + 35
