Bro , I can answer it , but I have a confusion.
Is it ur q , 8 * 2^( 2 x ) + ( 4*2^x ) + 1 = 1 + ( 2^ x)
Yep
You r right
Its answer is -3 but I want to know steps

Given expression is
8×2^2x + 4×2^x + 1 = 1 + 2x
Let 2x = t, we get 8t2+4t+1 = 1+t⇒8t2+4t = t⇒8t2+3t = 0⇒t(8t+3) = 0⇒t = 0 or t = −38⇒2x = 0 or 2x = −38
Now, 2x will always be greater than 0, that means, it will always be positive.Thus, both the final expressions do not lead to any solution.
