Solve the equation.

81x^2+4=0

Step 1: Subtract 4 from both sides.

81x^2+4=0

81x^2=-4

Step 2: Divide both sides by 81.

81x^2/81=-4/81

x^2=-4/81

Step 3: Take square root.

x=±

No real solutions.

y = 2x

step-by-step explanation:

if you divide each number in the sequence, you'll see that they all have a multiple factor of 2. each number in the series, and any other numbers which may continue, will be multiplied by 2. therefore, y is the next number in the sequence, and x is the current one, so, our formula will be y = 2x.
