Help please within the next hour Amira is solving the equation x2 – 6x = 1. Which value must be added to both sides of the equation to make the left side a perfect-square trinomial?
a. –9
b. 8
c. 9
d. 36

c. 9

To complete the square, you take half of the coefficient of b and square it. It's important to note that the value being added will always be positive.

2 and 1.

step-by-step explanation:

plug in each answer. 0 doesn't work, 1 does. so does 2. 4 doesn't:

0 = 1 is not true.

2 = 2 is true.

4 = 4 is true.

8 = 16 is not true.

hope this !
