If f(x)=25-x^2 and g(x)=x+5, what is (f/g)(x)?
elena-s [515]

Answer:

\frac{f(x)}{g(x)} = (5-x)

Step-by-step explanation:

f(x)=25-x^2 and g(x)=x+5

We need to find (f/g)(x)

(f/g)(x) = f(x)/ g(x)

we divide f(x) by g(x)  and then we simplify

\frac{f(x)}{g(x)} = \frac{25-x^2}{x+5}

WE factor 25-x^2

25-x^2 = 5^2 - x^2 = (5-x)(5+x)

\frac{f(x)}{g(x)} = \frac{25-x^2}{x+5}

\frac{f(x)}{g(x)} = \frac{(5-x)(5+x)}{x+5}

5+x or x+5  are same , so we cancel out x+5

\frac{f(x)}{g(x)} = (5-x)
