 Question from Lloyd, a student: Solve the equation 2^2x + 3(2^x) - 4 = 0

Hi Lloyd,

I can give you a hint.

$2^{2x} = \left(2^x\right)^{2}.$

Write back if you need more assistance,
Penny

Hi Penny

Please give me more hints I believe I will catch up.

Lloyd,

After you have rewritten the equation with $2^{2x}$ replaced as I suggested above, let $y = 2^x$ and see if you can deal with the resulting equation.
