Simplifying 4x2 + 26x + -47 = 0 Reorder the terms: -47 + 26x + 4x2 = 0 Solving -47 + 26x + 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'. -11.75 + 6.5x + x2 = 0 Move the constant term to the right: Add '11.75' to each side of the equation. -11.75 + 6.5x + 11.75 + x2 = 0 + 11.75 Reorder the terms: -11.75 + 11.75 + 6.5x + x2 = 0 + 11.75 Combine like terms: -11.75 + 11.75 = 0.00 0.00 + 6.5x + x2 = 0 + 11.75 6.5x + x2 = 0 + 11.75 Combine like terms: 0 + 11.75 = 11.75 6.5x + x2 = 11.75 The x term is 6.5x. Take half its coefficient (3.25). Square it (10.5625) and add it to both sides. Add '10.5625' to each side of the equation. 6.5x + 10.5625 + x2 = 11.75 + 10.5625 Reorder the terms: 10.5625 + 6.5x + x2 = 11.75 + 10.5625 Combine like terms: 11.75 + 10.5625 = 22.3125 10.5625 + 6.5x + x2 = 22.3125 Factor a perfect square on the left side: (x + 3.25)(x + 3.25) = 22.3125 Calculate the square root of the right side: 4.723610907 Break this problem into two subproblems by setting (x + 3.25) equal to 4.723610907 and -4.723610907.Subproblem 1
x + 3.25 = 4.723610907 Simplifying x + 3.25 = 4.723610907 Reorder the terms: 3.25 + x = 4.723610907 Solving 3.25 + x = 4.723610907 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-3.25' to each side of the equation. 3.25 + -3.25 + x = 4.723610907 + -3.25 Combine like terms: 3.25 + -3.25 = 0.00 0.00 + x = 4.723610907 + -3.25 x = 4.723610907 + -3.25 Combine like terms: 4.723610907 + -3.25 = 1.473610907 x = 1.473610907 Simplifying x = 1.473610907Subproblem 2
x + 3.25 = -4.723610907 Simplifying x + 3.25 = -4.723610907 Reorder the terms: 3.25 + x = -4.723610907 Solving 3.25 + x = -4.723610907 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-3.25' to each side of the equation. 3.25 + -3.25 + x = -4.723610907 + -3.25 Combine like terms: 3.25 + -3.25 = 0.00 0.00 + x = -4.723610907 + -3.25 x = -4.723610907 + -3.25 Combine like terms: -4.723610907 + -3.25 = -7.973610907 x = -7.973610907 Simplifying x = -7.973610907Solution
