PLEASE HELP! WILL MARK BRAINLIEST IF CORRECT

Which value of c completes the square in the expression x2 + 14x + c?

A. –49
B. –7
C. 7
D. 49

Answer 1

Answer:

D. 49

Step-by-step explanation:

To complete the square, you have to take half of the value next to x, 14 in this case, and square that.

1/2 of  14 is 7

7 squared is 49

so, the final equation is x²+14x+49
