B. The coefficientsExplanation
In the quadratic equation in the AC Method, A, B, and C represent the coefficients. The coefficients are the constants that multiply the variables in the equation. A represents the coefficient of the quadratic term, B represents the coefficient of the linear term, and C represents the constant term. These coefficients determine the shape and position of the quadratic curve. The x-values and y-values, on the other hand, represent the values of the variables and the corresponding output of the equation, respectively.Rate this question:

Correct Answer
C. Ac + bExplanation
The correct expression to solve for in the AC Method is ac + b. This method is used to factor quadratic equations of the form ax^2 + bx + c. The AC Method involves finding two numbers, a and c, whose product is equal to ac and whose sum is equal to b. By factoring the quadratic equation using these two numbers, we can find the roots of the equation. Therefore, the correct expression to solve for in the AC Method is ac + b.Rate this question:

Using the AC method, what is the factored form of the quadratic equation x² - 8x + 15 = 0?
- A.
(x - 5)(x - 3)
- B.

- C.
(x + 5)(x + 3)
- D.
(x + 3)(x - 5)
Correct Answer
A. (x - 5)(x - 3)Explanation
The factored form of a quadratic equation can be found using the AC method, which involves finding two numbers that multiply to give the product of the coefficient of x² and the constant term (in this case, 1 * 15 = 15) and also add up to give the coefficient of x (in this case, -8). The numbers that satisfy these conditions are -5 and -3. Therefore, the factored form of the quadratic equation x² - 8x + 15 = 0 is (x - 5)(x - 3).Rate this question:

- C.
(x + 2)(2x - 3)
- D.
(2x - 1)(x + 3)
Correct Answer
D. (2x - 1)(x + 3)Explanation
The factored form of the equation 2x² +5x - 3 using the AC method is (2x - 1)(x + 3). This can be found by finding two numbers whose product is equal to the product of the coefficient of the x² term (2) and the constant term (-3), which is -6. The numbers that satisfy this condition are -1 and 6. Then, these numbers are used to split the middle term (-7x) into two terms (-1x and -6x) and factor by grouping. This leads to the factored form of (2x - 1)(x + 3).Rate this question:

- A.
-6
- B.
6
- C.

- D.
3
Correct Answer
A. -6Explanation
In the AC method, we need to find two numbers, A and C, such that their product is equal to the product of the coefficient of x² and the constant term (in this case, 3 * -2 = -6). Additionally, these two numbers must add up to the coefficient of x (in this case, -1). By trial and error, we can determine that the numbers -3 and 2 satisfy these conditions (-3 * 2 = -6 and -3 + 2 = -1). Therefore, the value of AC in the AC method for this quadratic equation is -6.Rate this question:

Correct Answer
A. -1 and 6Explanation
The pair -1 and 6 adds up to 5 and multiplies to -6. In the given quadratic equation, the coefficient of x is 5 and the constant term is -3. By factoring the quadratic equation, we need to find two numbers that add up to 5 and multiply to -6. The pair -1 and 6 satisfies these conditions, as -1 + 6 = 5 and -1 * 6 = -6. Therefore, the pair -1 and 6 is the correct answer.Rate this question:
