Your answer would be C. This is because you must find factors of c that multiply to c itself, but add to -14(b). -7×-7 equals 49, but they add to -14.

For this case we must obtain the value of "c" to complete squares.

If we have:

[tex]y ^ 2-14y + c[/tex]

To complete squares we do the following:

We divide the middle term by 2 and raise the expression squared. That will be the value of "c", that is:

[tex]c = (\frac {-14} {2}) ^ 2\\c = 49\\ y^ 2-14y + 49[/tex]

Answer:

[tex]c = 49[/tex]

Option C
