Question

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

Answer 1

`{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? ☺️
