What number "c" completes the square: x^2 - 14x + c

Vladimir79 [104]

Answer:

49

Step-by-step explanation:

To complete the square we use the formula:

$c=(\frac{b}{2} )^{2}$

So we can plug in 14 for b to find c.

$c=(\frac{14}{2} )^{2}\\\\c=(7 )^{2}\\c=49$

Now this equation can be factored into:

$(x-7)^{2}$
