Simplifying 4x2 + 2 + 17x + 15 = 0 Reorder the terms: 2 + 15 + 17x + 4x2 = 0 Combine like terms: 2 + 15 = 17 17 + 17x + 4x2 = 0 Solving 17 + 17x + 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'. 4.25 + 4.25x + x2 = 0 Move the constant term to the right: Add '-4.25' to each side of the equation. 4.25 + 4.25x + -4.25 + x2 = 0 + -4.25 Reorder the terms: 4.25 + -4.25 + 4.25x + x2 = 0 + -4.25 Combine like terms: 4.25 + -4.25 = 0.00 0.00 + 4.25x + x2 = 0 + -4.25 4.25x + x2 = 0 + -4.25 Combine like terms: 0 + -4.25 = -4.25 4.25x + x2 = -4.25 The x term is 4.25x. Take half its coefficient (2.125). Square it (4.515625) and add it to both sides. Add '4.515625' to each side of the equation. 4.25x + 4.515625 + x2 = -4.25 + 4.515625 Reorder the terms: 4.515625 + 4.25x + x2 = -4.25 + 4.515625 Combine like terms: -4.25 + 4.515625 = 0.265625 4.515625 + 4.25x + x2 = 0.265625 Factor a perfect square on the left side: (x + 2.125)(x + 2.125) = 0.265625 Calculate the square root of the right side: 0.515388203 Break this problem into two subproblems by setting (x + 2.125) equal to 0.515388203 and -0.515388203.Subproblem 1
x + 2.125 = 0.515388203 Simplifying x + 2.125 = 0.515388203 Reorder the terms: 2.125 + x = 0.515388203 Solving 2.125 + x = 0.515388203 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-2.125' to each side of the equation. 2.125 + -2.125 + x = 0.515388203 + -2.125 Combine like terms: 2.125 + -2.125 = 0.000 0.000 + x = 0.515388203 + -2.125 x = 0.515388203 + -2.125 Combine like terms: 0.515388203 + -2.125 = -1.609611797 x = -1.609611797 Simplifying x = -1.609611797Subproblem 2
x + 2.125 = -0.515388203 Simplifying x + 2.125 = -0.515388203 Reorder the terms: 2.125 + x = -0.515388203 Solving 2.125 + x = -0.515388203 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-2.125' to each side of the equation. 2.125 + -2.125 + x = -0.515388203 + -2.125 Combine like terms: 2.125 + -2.125 = 0.000 0.000 + x = -0.515388203 + -2.125 x = -0.515388203 + -2.125 Combine like terms: -0.515388203 + -2.125 = -2.640388203 x = -2.640388203 Simplifying x = -2.640388203Solution
