Given 22x +8+1 = 32. 2x => 28.22x +1 = 32. 2x
=> 256. (2x)² -32. 2x +1 = 0
Putting 2x = t, we get, 256 t² -32t +1 = 0
=> t = [-(-32) + (- 32)² -4 (256)(1)]/[2 (256)] = (32 ± 0)/512 = 1/16, 1/16
But t = 2x. Hence 2x = t = 1, 1 = 2-4, 2-4
=> x = -4, -4
Hence the solution of the given equation is x = -4
