Blaine Fox · Answer 1

12.25

Step-by-step explanation:

To find the c value in the equation, we need to divide b by two and then square it.

b = - 7 and - 7/2 is 3.5

Then we square 3.5 and we get 12.25

Roach · Answer 2

(x+0) ^2-7

Step-by-step explanation:

x^2-7 to complete the square use the formula (b/2) ^2 in order to create a new term.

ax^2+bx+c in this case b=0

(x+0) ^2-7

hope it works
