a * x^3 + b * x^2 + c * x + d = 0
Students had to factor the polynomial equation and determine the values of a, b, c, and d that satisfied the equation. This question assessed their ability to apply factoring techniques and use the Rational Root Theorem to find the correct answers.
Question 5
The fifth question focused on solving a rational equation. It required students to find the values of the variable that made the equation true. The equation provided was:
(a * x + b) / (c * x + d) = e
Students had to solve for x and determine the values of a, b, c, d, and e in the equation. This question assessed their understanding of rational expressions and their ability to simplify complex equations.
Exam Analysis
Question 1
The first question tested students' proficiency in factoring quadratic equations. By factoring the given equation, they could determine the values of a, b, and c, which were 1, -5, and 6, respectively. The correct factored form of the equation was (x - 2)(x - 3) = 0. Therefore, the roots of the equation were x = 2 and x = 3, and the correct answer was (2, 3).
Question 2
The second question assessed students' understanding of exponential functions. By solving the given equation, students could determine the values of a, b, and c, which were 4, 2, and 8, respectively. Using logarithmic functions, they could find the value of x, which was 3. Therefore, the correct answer was 3.
Question 3
The third question focused on solving a system of linear equations. By using the method of substitution or elimination, students could find the values of x and y that satisfied both equations. The correct solution set was (1, 3), and the system was consistent. Therefore, the correct answer was (1, 3) consistent.
Question 4
The fourth question assessed students' ability to find the zeros or roots of a polynomial equation. By factoring the given equation, they could determine the values of a, b, c, and d, which were 1, -4, -45, and 100, respectively. The correct factored form of the equation was (x - 5)(x + 3)(x - 4) = 0. Therefore, the roots of the equation were x = 5, x = -3, and x = 4, and the correct answer was (5, -3, 4).
Question 5
The fifth question focused on solving a rational equation. By solving the given equation, students could determine the values of a, b, c, d, and e, which were 1, 3, -2, -1, and 2, respectively. The correct solution to the equation was x = -1. Therefore, the correct answer was -1.
