Simplifying 4x2 + 7x + -29 = 0 Reorder the terms: -29 + 7x + 4x2 = 0 Solving -29 + 7x + 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'. -7.25 + 1.75x + x2 = 0 Move the constant term to the right: Add '7.25' to each side of the equation. -7.25 + 1.75x + 7.25 + x2 = 0 + 7.25 Reorder the terms: -7.25 + 7.25 + 1.75x + x2 = 0 + 7.25 Combine like terms: -7.25 + 7.25 = 0.00 0.00 + 1.75x + x2 = 0 + 7.25 1.75x + x2 = 0 + 7.25 Combine like terms: 0 + 7.25 = 7.25 1.75x + x2 = 7.25 The x term is 1.75x. Take half its coefficient (0.875). Square it (0.765625) and add it to both sides. Add '0.765625' to each side of the equation. 1.75x + 0.765625 + x2 = 7.25 + 0.765625 Reorder the terms: 0.765625 + 1.75x + x2 = 7.25 + 0.765625 Combine like terms: 7.25 + 0.765625 = 8.015625 0.765625 + 1.75x + x2 = 8.015625 Factor a perfect square on the left side: (x + 0.875)(x + 0.875) = 8.015625 Calculate the square root of the right side: 2.831187913 Break this problem into two subproblems by setting (x + 0.875) equal to 2.831187913 and -2.831187913.Subproblem 1
x + 0.875 = 2.831187913 Simplifying x + 0.875 = 2.831187913 Reorder the terms: 0.875 + x = 2.831187913 Solving 0.875 + x = 2.831187913 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-0.875' to each side of the equation. 0.875 + -0.875 + x = 2.831187913 + -0.875 Combine like terms: 0.875 + -0.875 = 0.000 0.000 + x = 2.831187913 + -0.875 x = 2.831187913 + -0.875 Combine like terms: 2.831187913 + -0.875 = 1.956187913 x = 1.956187913 Simplifying x = 1.956187913Subproblem 2
x + 0.875 = -2.831187913 Simplifying x + 0.875 = -2.831187913 Reorder the terms: 0.875 + x = -2.831187913 Solving 0.875 + x = -2.831187913 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-0.875' to each side of the equation. 0.875 + -0.875 + x = -2.831187913 + -0.875 Combine like terms: 0.875 + -0.875 = 0.000 0.000 + x = -2.831187913 + -0.875 x = -2.831187913 + -0.875 Combine like terms: -2.831187913 + -0.875 = -3.706187913 x = -3.706187913 Simplifying x = -3.706187913Solution
