1.(s+4)^2
=s^2+8s+16
2. (w-5)^2
=w^2-10w+25
3.(e-7)^2
=e^2+14e+49

Can you answer my more question ?
your answer is wrong... sorry... i'll copy you're example and then try to see it
1.(s+4)^2
=s^2+8s+16
2. (w-5)^2
=w^2-10w+25
3.(e-7)^2
=e^2+14e+49

1.(s+4)^2 or (s+4)²
=s²+4²
2. (w-5)^2 or (w-5)²
=w²-5² or w²-25 ( im not sure )
3.(e-7)^2 or (e-7)²
=e²-7² or e²-49 ( im not sure _
