Advanced Math practice question

Answer: 11

(x + 1)(x + 2) = x² + 3x + 2; multiplying by (x + 3) gives x³ + 6x² + 11x + 6. So b = 11.

Common wrong answers

If you answered 5

5 is 2 + 3, the sum of two of the constants, not the coefficient of x.

If you answered 6

6 is a (or c), not b.

If you answered 23

23 is a + b + c.
