Step-by-step explanation:
3x squared - 5x - 1 equals 0 using the method of completing the square he gets 3 x square - 5 x equals one and then x squared - 5/3 x is equal to 1 what does dividing should I pray then you come down you get X squared - 5/3 x into (- 5/6 or squared is equals 1/3 + but it will be negative 5/6 or squared you good like them send any you get so at the end your roots are going to be x equals 1.847 or x equals negative 0.180 results
