Simplifying 2x2 + 26x + 25 = 0 Reorder the terms: 25 + 26x + 2x2 = 0 Solving 25 + 26x + 2x2 = 0 Solving for variable 'x'. Begin completing the square. Divide all terms by 2 the coefficient of the squared term: Divide each side by '2'. 12.5 + 13x + x2 = 0 Move the constant term to the right: Add '-12.5' to each side of the equation. 12.5 + 13x + -12.5 + x2 = 0 + -12.5 Reorder the terms: 12.5 + -12.5 + 13x + x2 = 0 + -12.5 Combine like terms: 12.5 + -12.5 = 0.0 0.0 + 13x + x2 = 0 + -12.5 13x + x2 = 0 + -12.5 Combine like terms: 0 + -12.5 = -12.5 13x + x2 = -12.5 The x term is 13x. Take half its coefficient (6.5). Square it (42.25) and add it to both sides. Add '42.25' to each side of the equation. 13x + 42.25 + x2 = -12.5 + 42.25 Reorder the terms: 42.25 + 13x + x2 = -12.5 + 42.25 Combine like terms: -12.5 + 42.25 = 29.75 42.25 + 13x + x2 = 29.75 Factor a perfect square on the left side: (x + 6.5)(x + 6.5) = 29.75 Calculate the square root of the right side: 5.454356057 Break this problem into two subproblems by setting (x + 6.5) equal to 5.454356057 and -5.454356057.Subproblem 1
x + 6.5 = 5.454356057 Simplifying x + 6.5 = 5.454356057 Reorder the terms: 6.5 + x = 5.454356057 Solving 6.5 + x = 5.454356057 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-6.5' to each side of the equation. 6.5 + -6.5 + x = 5.454356057 + -6.5 Combine like terms: 6.5 + -6.5 = 0.0 0.0 + x = 5.454356057 + -6.5 x = 5.454356057 + -6.5 Combine like terms: 5.454356057 + -6.5 = -1.045643943 x = -1.045643943 Simplifying x = -1.045643943Subproblem 2
x + 6.5 = -5.454356057 Simplifying x + 6.5 = -5.454356057 Reorder the terms: 6.5 + x = -5.454356057 Solving 6.5 + x = -5.454356057 Solving for variable 'x'.
