Find (f×g)(x) when f(x)=x^2+8x+15 and g(x)=5 over x^2-9

Answers

look at the picture......

Final answer:

To find the product of two functions, substitute the given functions into the expression and simplify.

Explanation:

To find (f×g)(x), we need to multiply the functions f(x) and g(x). First, let's substitute f(x) = x^2 + 8x + 15 and g(x) = 5/(x^2 - 9) into the expression. (f×g)(x) = (x^2 + 8x + 15) × (5/(x^2 - 9)).

Next, we simplify the expression by multiplying the numerators and denominators. (f×g)(x) = 5(x^2 + 8x + 15) / (x^2 - 9).

We can further simplify by factoring the numerator and denominator if possible. If not, we can leave the expression as is. Therefore, (f×g)(x) = 5(x + 5)(x + 3) / (x - 3)(x + 3).
