Find the value of c that completes the square x^2+7x+c

Please help me with how to do this, and show me. Thank you.

c =

Step-by-step explanation:

Given

x² + 7x + c

To complete the square

add ( half the coefficient of the x- term )² to x² + 7x

x² + 2( )x + , thus

= (x + )² ← a perfect square

with c =

1     sepan

2     encuentren

3     tenga

4     hable

5   parezca

6   llegue

false

step-by-step explanation:

the reason i say this is because for a certain length of sides you can pick any two and the length is wither equal or greater than the third side and in this case it's not.

3 + 5 = 8

8 is smaller than 9 which is the third side.

hope this : )
