Advanced Math practice question

Answer: 1

Multiplying by 2x(x + 1): 2(x + 1) + 2x = 3x(x + 1), so 3x² − x − 2 = 0 and (3x + 2)(x − 1) = 0. The positive solution is 1.

Common wrong answers

If you answered 2

2 gives 1/2 + 1/3 = 5/6.

If you answered -0.67

−2/3 is the negative solution.

If you answered 0.5

0.5 gives 2 + 2/3.
