Question: What is the value of the discriminant for the equation 3x² + 6x + 2 = 0? (2020)

Options:

Correct Answer: 4

Exam Year: 2020

Solution:

The discriminant D = b² - 4ac = 6² - 4*3*2 = 36 - 24 = 12.

What is the value of the discriminant for the equation 3x² + 6x + 2 = 0? (2020)

What is the value of the discriminant for the equation 3x² + 6x + 2 = 0? (2020)

Step 1: Identify the coefficients a, b, and c from the equation 3x² + 6x + 2 = 0. Here, a = 3, b = 6, and c = 2.
Step 2: Write the formula for the discriminant, which is D = b² - 4ac.
Step 3: Substitute the values of a, b, and c into the formula. This gives us D = 6² - 4 * 3 * 2.
Step 4: Calculate 6², which is 36.
Step 5: Calculate 4 * 3 * 2, which is 24.
Step 6: Subtract 24 from 36 to find the discriminant: 36 - 24 = 12.
Step 7: Conclude that the value of the discriminant D is 12.
