• Do you need help solving algebra problems regardless of that title?

Example: $$4^x + 2^x+1 = 3$$

1. Find the common denominator for the numerator: $(x+y)(x-y) = x^2 - y^2$.
2. Numerator becomes $x(x-y) - x(x+y) = x^2 - xy - x^2 - xy = -2xy$.
3. Denominator becomes $y(x-y) + y(x+y) = xy - y^2 + xy + y^2 = 2xy$.
4. Result: $\frac-2xy2xy = -1$.
