Question: If the quadratic equation x² - 5x + 6 = 0 is factored, which of the following pairs of numbers represents the roots?

Options:

Correct Answer: 2 and 3

Solution:

Factoring the equation gives (x - 2)(x - 3) = 0, thus the roots are 2 and 3.

If the quadratic equation x² - 5x + 6 = 0 is factored, which of the following pairs of numbers represents the roots?

If the quadratic equation x² - 5x + 6 = 0 is factored, which of the following pairs of numbers represents the roots?

Step 1: Start with the quadratic equation x² - 5x + 6 = 0.
Step 2: Look for two numbers that multiply to 6 (the constant term) and add up to -5 (the coefficient of x).
Step 3: The numbers that work are -2 and -3 because -2 * -3 = 6 and -2 + -3 = -5.
Step 4: Rewrite the quadratic equation using these numbers: (x - 2)(x - 3) = 0.
Step 5: Set each factor equal to zero: x - 2 = 0 and x - 3 = 0.
Step 6: Solve for x in each equation: x = 2 and x = 3.
Step 7: The roots of the equation are 2 and 3.
