Question

Solve the quadratic equation
81x^2=16

Answer 1

To solve the quadratic equation 81x^2 = 16, we can take the square root of both sides of the equation and solve for x.

Step-by-step explanation:

To solve the quadratic equation 81x^2 = 16, we can take the square root of both sides of the equation:

√(81x^2) = √16

9x = ±4

Divide both sides by 9 to solve for x:

x = ±(4/9)

Therefore, the solutions to the quadratic equation are x = 4/9 and x = -4/9.
