Simplifying 4x2 + -40x + 55 = 0 Reorder the terms: 55 + -40x + 4x2 = 0 Solving 55 + -40x + 4x2 = 0 Solving for variable 'x'. Begin completing the square. Divide all terms by 4 the coefficient of the squared term: Divide each side by '4'. 13.75 + -10x + x2 = 0 Move the constant term to the right: Add '-13.75' to each side of the equation. 13.75 + -10x + -13.75 + x2 = 0 + -13.75 Reorder the terms: 13.75 + -13.75 + -10x + x2 = 0 + -13.75 Combine like terms: 13.75 + -13.75 = 0.00 0.00 + -10x + x2 = 0 + -13.75 -10x + x2 = 0 + -13.75 Combine like terms: 0 + -13.75 = -13.75 -10x + x2 = -13.75 The x term is -10x. Take half its coefficient (-5). Square it (25) and add it to both sides. Add '25' to each side of the equation. -10x + 25 + x2 = -13.75 + 25 Reorder the terms: 25 + -10x + x2 = -13.75 + 25 Combine like terms: -13.75 + 25 = 11.25 25 + -10x + x2 = 11.25 Factor a perfect square on the left side: (x + -5)(x + -5) = 11.25 Calculate the square root of the right side: 3.354101966 Break this problem into two subproblems by setting (x + -5) equal to 3.354101966 and -3.354101966.Subproblem 1
x + -5 = 3.354101966 Simplifying x + -5 = 3.354101966 Reorder the terms: -5 + x = 3.354101966 Solving -5 + x = 3.354101966 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right.
