The expression $(x + 4)(x + 6)$ is equivalent to $x^2 + bx + 24$ , where $b$ is a constant. What is the value of $b$ ?

Student-produced response: enter your answer.

Show answer and explanation

Answer: 10

Expand: $x^2 + 6x + 4x + 24 = x^2 + 10x + 24$ . So $b = 10$ .

Answering 24 multiplies the constants, which gives the constant term, not $b$ .
