Answer 2

To evaluate the expression 5x^3 - x^2 - 5x + 1 when x takes the value 0.2, we can substitute the value of x into the expression and perform the calculations.

When x = 0.2, the expression becomes:

5(0.2)^3 - (0.2)^2 - 5(0.2) + 1

Now, let's simplify it:

5(0.008) - 0.04 - 1 + 1

0.04 - 0.04

0

Therefore, when x = 0.2, the expression 5x^3 - x^2 - 5x + 1 evaluates to 0.
