Advanced Math practice question
For x ≠ 0, the expression (6x² + 9x)/(3x) simplifies to ax + b, where a and b are constants. What is the value of a + b?
Answer: 5
6x²/(3x) = 2x and 9x/(3x) = 3, so a = 2, b = 3, and a + b = 5.
Common wrong answers
- If you answered 2
- 2 is a alone.
- If you answered 3
- 3 is b alone.
- If you answered 15
- 15 adds the original coefficients 6 and 9.
