Answer 2

To perform the process of completing the square for the expression c^2 - 4c - 3, follow these steps:

Step 1: Group the terms Rearrange the expression by grouping the first two terms together and leaving the constant term separate:

c^2 - 4c - 3 = (c^2 - 4c) - 3

Step 2: Add and subtract the square of half the coefficient of the c term inside the parentheses The coefficient of the c term is -4. Half of it is -4/2 = -2. We'll add and subtract (-2)^2 inside the parentheses:

(c^2 - 4c) - 3 + (-2)^2 - (-2)^2

Step 3: Factor the square inside the parentheses Simplify the expression inside the parentheses:

(c^2 - 4c) - 3 + 4 - 4

Step 4: Complete the square Combine the constant terms:

c^2 - 4c + 1

Step 5: Write the expression as a squared binomial The final step is to write the expression as a squared binomial:

(c - 2)^2

So, the complete square of the expression c^2 - 4c - 3 is (c - 2)^2.
