Question

Solve for n 36n2 - 23 = 58 write your answer as intergers or as proper or improper fractions in simplest form

Answer 1

n = ±
`(3)/(2)`

Explanation:

given

36n² - 23 = 58 ( add 23 to both sides )

36n² = 81 ( divide both sides by 36 )

n² =
`(81)/(36)` ( take square root of both sides )

`√(n^2)` = ±
`\sqrt{(81)/(36) }` , that is

n = ±
`(√(81) )/(√(36) )` = ±
`(9)/(6)` = ±
`(3)/(2)`
