First, write the "square of the first term"
Second, write the " product of first and second term"
Lastly, write the "square of the last term"
Di ko makita pic eh mejo malabo.... hope this helps....
If your finding is just the Square of Binomial of the given, then the answer would be; 4^2x - 8^x + 4 . But if your finding for "x" then i guess you'll have to use logarithmic and exponential functions. I hope this help :)
