Explanation
The correct answer is 3. The solution to the given equation can be found by factoring the quadratic expression. The factors can be determined by finding two numbers with a sum of 1 and a product of . The two numbers that meet these constraints are 4 and . Therefore, the given equation can be rewritten as . It follows that the solutions to the equation are or . Since it is given that , a must equal 3.
