Question

Use any method to solve the equation. If necessary, round to the nearest hundredth. 9x^2=17

Answer 1

9x² = 17

x² = (17/9)
x = √(17/9) , x' = √(3)/3 = 1.37 and x" = -  1.37

Answer 2

9x^2 = 17...divide both sides by 9
x^2 = 17/9 or 1.89....take square root of both sides, eliminating the ^2
x = (+-) sqrt 1.89
x = (+-) 1.37 <==
