one of the solution to this problem below is 8. what is the other solution? C^2-64=0 ( please show your work )

${c}^{2} - 64 = 0$
This can also be represented as:
${c}^{2} - {8}^{2} = 0$
Using difference of two squares;
$(c - 8)(c + 8) = 0$
$c - 8 = 0 \: or \: c + 8 = 0 \\ \\ c = 8 \: or \: c = - 8$

Hope I helped? ☺️

It is possible for two different inputs to give you the same output. For example, -2 and 2 produce the same result: 5.

it is not possible to derive two different outputs from the same input. This is because a) $y=x^2+1$ is a function making it impossible to have two outputs and b) for each value, if you square it, you only get one value, then adding one, making it one certain value.
