Let's solve for c.

x2+18x+c=25+c

Step 1: Add -c to both sides.

x2+c+18x+−c=c+25+−c

x2+18x=25

Step 2: Add -x^2 to both sides.

x2+18x+−x2=25+−x2

18x=−x2+25

Step 3: Add -18x to both sides.

18x+−18x=−x2+25+−18x

0=−x2−18x+25

Step 4: Divide both sides by 0.

00=−x2−18x+250

c=−x2−18x+250

Answer:

c=−x2−18x+250
