Assignment 4: Using Quadratic Equation

For 1-4
Use the quadratic equation to find the roots of each of the following functions.
List the values of a, b, and c.

1.  y = x^2 – 5x + 6

2.  y = x^2 – 5x + 1

3.  y = 4x^2 – 32

4.  y = 2x^2 – 7x – 4

For 5-8
Solve the following equations using the quadratic equation.
If an equation has no real solution then indicate “no real solution”
List the values of a, b, and c.

5.  2x^2 – 7x – 4 = -25

6.  0 = x^2 – 4x – 12

7.  x^2 – 4x – 12 = 9

8.  5 = x^2 – 8x + 12

9.  List the possible amount of solutions that can occur with a quadratic function?

10.  Explain what will be true about a, b, and c when there is only one solution.
