64x^(2) - 5 = 11
Equate to zero , by subtracting '11' from both sides.
Hence
64x^(2) - 16 = 0
Algebraically rearrange
(8x)^(2) - 4^(2) = 0
We now have two squared terms with a negative between them. This factors to :-
(8x - 4)(8x + 4) = 0 Note the different signs in each brackets.
Hence
8x - 4 = 0
8x = 4
x - 4/8
x = 1/2
&
8x + 4 = 0
8x = -4
x = -4/8
x = -1/2
So the two solutions are x = 1/2 & x = -1/2
NB Twosquared terms with a POSITIVE(+) between them , does NOT factor.
