1. Use the quadratic equation x^2 + 18x = 25 to answer the following questions.

Part A: Find the value of c that will result in a perfect square trinomial.
x^2 + 18x + c = 25 + c

Part B: Rewrite the above equation into a perfect square binomial form.
( x + ? )^2 = ?

Part C: What is the value of x?

2. Find the roots of the quadratic function by completing the square:
x^2 + 4x - 1 = 0.
