Simplifying 4x2 + 19x + -4 = 0 Reorder the terms: -4 + 19x + 4x2 = 0 Solving -4 + 19x + 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'. -1 + 4.75x + x2 = 0 Move the constant term to the right: Add '1' to each side of the equation. -1 + 4.75x + 1 + x2 = 0 + 1 Reorder the terms: -1 + 1 + 4.75x + x2 = 0 + 1 Combine like terms: -1 + 1 = 0 0 + 4.75x + x2 = 0 + 1 4.75x + x2 = 0 + 1 Combine like terms: 0 + 1 = 1 4.75x + x2 = 1 The x term is 4.75x. Take half its coefficient (2.375). Square it (5.640625) and add it to both sides. Add '5.640625' to each side of the equation. 4.75x + 5.640625 + x2 = 1 + 5.640625 Reorder the terms: 5.640625 + 4.75x + x2 = 1 + 5.640625 Combine like terms: 1 + 5.640625 = 6.640625 5.640625 + 4.75x + x2 = 6.640625 Factor a perfect square on the left side: (x + 2.375)(x + 2.375) = 6.640625 Calculate the square root of the right side: 2.576941016 Break this problem into two subproblems by setting (x + 2.375) equal to 2.576941016 and -2.576941016.Subproblem 1
x + 2.375 = 2.576941016 Simplifying x + 2.375 = 2.576941016 Reorder the terms: 2.375 + x = 2.576941016 Solving 2.375 + x = 2.576941016 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-2.375' to each side of the equation. 2.375 + -2.375 + x = 2.576941016 + -2.375 Combine like terms: 2.375 + -2.375 = 0.000 0.000 + x = 2.576941016 + -2.375 x = 2.576941016 + -2.375 Combine like terms: 2.576941016 + -2.375 = 0.201941016 x = 0.201941016 Simplifying x = 0.201941016Subproblem 2
x + 2.375 = -2.576941016 Simplifying x + 2.375 = -2.576941016 Reorder the terms: 2.375 + x = -2.576941016 Solving 2.375 + x = -2.576941016 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-2.375' to each side of the equation. 2.375 + -2.375 + x = -2.576941016 + -2.375 Combine like terms: 2.375 + -2.375 = 0.000 0.000 + x = -2.576941016 + -2.375 x = -2.576941016 + -2.375 Combine like terms: -2.576941016 + -2.375 = -4.951941016 x = -4.951941016 Simplifying x = -4.951941016Solution
