If x is a real number, find \( x^2+2x(5-x)+(5-x)^2.\)
x^2 + 2x(5 - x) + (5- x)^2
x^2 + 2x(5) + 2x(-x) + 25 - x^2
x^2 - x^2 + 10x - 2x^2 + 25
-2x^2 + 10x + 25
If anyone wants to finish this or if it is finish tell me how I did.
x^2 + 2x(5 - x) + (5 - x)^2
x^2 + 10x - 2x^2 + x^2 - 10x + 25 =
25
Thanks !!!!!!!!!!!!!!1
