Question

What number must you add to complete the square? x2 + 14x = -5

Answer 1

44 is your answer

x2 + 14x = -5

must add 44 to complete the square

x2 + 14x +5 + 44
=x2 + 14x +49
=(x+7)^2

Answer 2

U take half of the x term and square it....then add to both sides

14/2 = 7.......7^2 = 49...so u add 49 to both sides
