A student is solving the problem x^2 + 10x+ ___ = 16 + ___ by the method of completing the square. What number should the studen

kvv77 [185]

Answer:

I believe it could be any number because:

let y=any number

x^2+10x+y=16+y

x^2+10x+y-y=16+y-y

x^2+10x=16

you can add any number to both side and not change the solution.
