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

x - 8 = -13 To solve the equation, you can add, subtract, multiply and/or divide as long as you do the same thing to both sides of the equation. In this case, you can add 8 to both sides making it x - 8 + 8 = -13 + 8 x = -5

x=13

The sum we need is (8/13) x 100= 61.54%
