The Discriminant oulev or ol orlo8 ooite Directions: Evaluate the expression b2 4ac given the following values of a, b and c. Then, answer the guide questions. Write your answer on the blanks. Example : a = 1 ; b = 4 ; c = -5 b2 - 4ac (4)2 - 4(1)(-5) 16 + 20 = 36 1. a = 1; b = -4 ; c = 3 2. a = 9; b = 6 ; c = 1 3. a = 3; b = -5 ; c = 5 %3D %3D %3D Questions: 1. What are the values you obtained from the activity? 2. Based from the activity, what type of numbers can be obtained from b2 - 4ac ? The discriminant of the quadratic equations ax2 + bx + c = 0 is the value of the- expression b2 - 4ac. This number is used to characterize the nature of a quadratic equation roots.
