Kaylin West · Answer 1

assuming x2 is x^2:

f (x) = (x+4) ^2 - 3

Step-by-step explanation:

1. move c to f (x) side

2. make sure a=1

3. (b/2) ^2

4. add the solution of 3 on both sides

5. factor the right side using the shortcut

6. add c back to the other side

Jason · Answer 2

Step-by-step explanation:

f (x) = x²+8x+13

f (x) = (x²+8x+16) - 16+13

f (x) = (x+4) ² - 3 ... vertex form
