Math Problem Statement

Ms. Johnson asked her students to match the number of solutions to the value of the discriminant. Select the correct answer in each row.

Solution

The image you uploaded is related to the discriminant in a quadratic equation of the form ax2+bx+c=0ax^2 + bx + c = 0. The discriminant is given by Δ=b24ac\Delta = b^2 - 4ac.

Here is how the discriminant affects the number of real solutions:

  • If Δ>0\Delta > 0: The quadratic equation has 2 real solutions (distinct real roots).
  • If Δ=0\Delta = 0: The quadratic equation has 1 real solution (a repeated real root).
  • If Δ<0\Delta < 0: The quadratic equation has no real solutions (complex/imaginary roots).

Now, let's match the rows to the correct categories:

  1. b24ac>0b^2 - 4ac > 02 Solutions (because the discriminant is positive, indicating two distinct real solutions).
  2. b24ac=0b^2 - 4ac = 01 Solution (because the discriminant is zero, indicating one repeated real solution).
  3. b24ac<0b^2 - 4ac < 0No Real Solutions (because the discriminant is negative, indicating complex solutions).

Correct answers:

  • b24ac>0b^2 - 4ac > 02 Solutions
  • b24ac=0b^2 - 4ac = 01 Solution
  • b24ac<0b^2 - 4ac < 0No Real Solutions

Do you need further clarification or have any questions on the discriminant? Here's a tip for your learning:

Tip: Remember that the discriminant determines the type of roots a quadratic equation has. Positive means two real roots, zero means one real root, and negative means no real roots!
