Question

81x^2 = 4 NEED HELP SOLVING QUADRATIC EQAUTIONS

Answer 1

x = ±
`(2)/(9)`

Explanation:

Given

81x² = 4 ( divide both sides by 81 )

x² =
`(4)/(81)` ( take the square root of both sides )

x = ±
`\sqrt{(4)/(81) }` = ±
`(√(4) )/(√(81) )` = ±
`(2)/(9)`

Answer 2

x=-+.222222 this is what I calculated
