What are the solutions to the equation of 8x squared -26x plus 15 equals 0 solved by completing the square?
Equation: 8x^2 -26x +15 =0 I
Divide all terms by 8: x^2 -26/8 +15/8 = 0 and complete the square as follows:-
(x -13/8)^2 -169/64 +15/8 = 0 => (x-13/8)^2 = 49/64
Square root both sides: x-13/8 = -/+ 7/8
Add 13/8 to both sides: x = 13/8 -/+ 7/8
Therefore solutions are: x = 5/2 or x = 3/4
