5 0
{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? ☺️

If 512+14=x then x=23 Question 10 options: True False
Inessa05 [86]
False!

if you plug in x, the equation would be 512+14= 23 which is incorrect. x would have to equal 526 for this statement to be considered true.
