Evaluate $f(0)$ when $f(x)=(x-5)(x+5)$
When $f(x)=(x-5)(x+5), f(0)=$
Final Answer: \(\boxed{-25}\)
Step 1 :Given the function $f(x)=(x-5)(x+5)$, we are asked to evaluate $f(0)$.
Step 2 :To find the value of $f(0)$, we substitute $x=0$ into the function $f(x)=(x-5)(x+5)$.
Step 3 :Substituting $x=0$ into the function gives $f(0)=(0-5)(0+5)$, which simplifies to $f(0)=-25$.
Step 4 :Final Answer: \(\boxed{-25}\)
