Simplifying 2x2 + 8x + -19 = 0 Reorder the terms: -19 + 8x + 2x2 = 0 Solving -19 + 8x + 2x2 = 0 Solving for variable 'x'. Begin completing the square. Divide all terms by 2 the coefficient of the squared term: Divide each side by '2'. -9.5 + 4x + x2 = 0 Move the constant term to the right: Add '9.5' to each side of the equation. -9.5 + 4x + 9.5 + x2 = 0 + 9.5 Reorder the terms: -9.5 + 9.5 + 4x + x2 = 0 + 9.5 Combine like terms: -9.5 + 9.5 = 0.0 0.0 + 4x + x2 = 0 + 9.5 4x + x2 = 0 + 9.5 Combine like terms: 0 + 9.5 = 9.5 4x + x2 = 9.5 The x term is 4x. Take half its coefficient (2). Square it (4) and add it to both sides. Add '4' to each side of the equation. 4x + 4 + x2 = 9.5 + 4 Reorder the terms: 4 + 4x + x2 = 9.5 + 4 Combine like terms: 9.5 + 4 = 13.5 4 + 4x + x2 = 13.5 Factor a perfect square on the left side: (x + 2)(x + 2) = 13.5 Calculate the square root of the right side: 3.674234614 Break this problem into two subproblems by setting (x + 2) equal to 3.674234614 and -3.674234614.Subproblem 1
x + 2 = 3.674234614 Simplifying x + 2 = 3.674234614 Reorder the terms: 2 + x = 3.674234614 Solving 2 + x = 3.674234614 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-2' to each side of the equation. 2 + -2 + x = 3.674234614 + -2 Combine like terms: 2 + -2 = 0 0 + x = 3.674234614 + -2 x = 3.674234614 + -2 Combine like terms: 3.674234614 + -2 = 1.674234614 x = 1.674234614 Simplifying x = 1.674234614Subproblem 2
x + 2 = -3.674234614 Simplifying x + 2 = -3.674234614 Reorder the terms: 2 + x = -3.674234614 Solving 2 + x = -3.674234614 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-2' to each side of the equation. 2 + -2 + x = -3.674234614 + -2 Combine like terms: 2 + -2 = 0 0 + x = -3.674234614 + -2 x = -3.674234614 + -2 Combine like terms: -3.674234614 + -2 = -5.674234614 x = -5.674234614 Simplifying x = -5.674234614Solution
The solution to the problem is based on the solutions from the subproblems. x = {1.674234614, -5.674234614}
