Advanced Math practice question

Answer: 1

2x = 1, so the expression is 1³ − 1² + 1 = 1 − 1 + 1 = 1.

Common wrong answers

If you answered 0

0 forgets the final + 2x.

If you answered 2

2 adds 1 + 1 without subtracting the middle term.

If you answered 0.375

0.375 evaluates x³ − x² + x at x = 1/2 without the factor 2.
