Final answer:
To simplify the polynomial function f(x) = 3x²(x+6)(x-5)², multiply the terms inside the parentheses and substitute the results back into the original expression.
Step-by-step explanation:
The polynomial function is f(x) = 3x²(x+6)(x-5)². To simplify this expression, start by multiplying the terms inside the parentheses:
- (x+6) = x * 6 = 6x
- (x-5)² = (x-5)(x-5) = x² - 5x - 5x + 25 = x² - 10x + 25
Now, substitute these results back into the original expression:
f(x) = 3x² * 6x * (x² - 10x + 25)
