To find the number of real roots of the equation \( x^3 - 6x + 9 = 0 \), we will follow these steps: ### Step 1: Define the function Let \( f(x) = x^3 - 6x + 9 \). ### Step 2: Find a potential root using trial and error We can start by testing some integer values to see if they yield a root. Let's try \( x = -3 \): ...
