Simplifying 4x2 + 30x + 25 = 0 Reorder the terms: 25 + 30x + 4x2 = 0 Solving 25 + 30x + 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'. 6.25 + 7.5x + x2 = 0 Move the constant term to the right: Add '-6.25' to each side of the equation. 6.25 + 7.5x + -6.25 + x2 = 0 + -6.25 Reorder the terms: 6.25 + -6.25 + 7.5x + x2 = 0 + -6.25 Combine like terms: 6.25 + -6.25 = 0.00 0.00 + 7.5x + x2 = 0 + -6.25 7.5x + x2 = 0 + -6.25 Combine like terms: 0 + -6.25 = -6.25 7.5x + x2 = -6.25 The x term is 7.5x. Take half its coefficient (3.75). Square it (14.0625) and add it to both sides. Add '14.0625' to each side of the equation. 7.5x + 14.0625 + x2 = -6.25 + 14.0625 Reorder the terms: 14.0625 + 7.5x + x2 = -6.25 + 14.0625 Combine like terms: -6.25 + 14.0625 = 7.8125 14.0625 + 7.5x + x2 = 7.8125 Factor a perfect square on the left side: (x + 3.75)(x + 3.75) = 7.8125 Calculate the square root of the right side: 2.795084972 Break this problem into two subproblems by setting (x + 3.75) equal to 2.795084972 and -2.795084972.Subproblem 1
x + 3.75 = 2.795084972 Simplifying x + 3.75 = 2.795084972 Reorder the terms: 3.75 + x = 2.795084972 Solving 3.75 + x = 2.795084972 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-3.75' to each side of the equation. 3.75 + -3.75 + x = 2.795084972 + -3.75 Combine like terms: 3.75 + -3.75 = 0.00 0.00 + x = 2.795084972 + -3.75 x = 2.795084972 + -3.75 Combine like terms: 2.795084972 + -3.75 = -0.954915028 x = -0.954915028 Simplifying x = -0.954915028Subproblem 2
x + 3.75 = -2.795084972 Simplifying x + 3.75 = -2.795084972 Reorder the terms: 3.75 + x = -2.795084972 Solving 3.75 + x = -2.795084972 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-3.75' to each side of the equation. 3.75 + -3.75 + x = -2.795084972 + -3.75 Combine like terms: 3.75 + -3.75 = 0.00 0.00 + x = -2.795084972 + -3.75 x = -2.795084972 + -3.75 Combine like terms: -2.795084972 + -3.75 = -6.545084972 x = -6.545084972 Simplifying x = -6.545084972Solution
