Simplifying 0.5x2 + 4x + -10 = 0 Reorder the terms: -10 + 4x + 0.5x2 = 0 Solving -10 + 4x + 0.5x2 = 0 Solving for variable 'x'. Begin completing the square. Divide all terms by 0.5 the coefficient of the squared term: Divide each side by '0.5'. -20 + 8x + x2 = 0 Move the constant term to the right: Add '20' to each side of the equation. -20 + 8x + 20 + x2 = 0 + 20 Reorder the terms: -20 + 20 + 8x + x2 = 0 + 20 Combine like terms: -20 + 20 = 0 0 + 8x + x2 = 0 + 20 8x + x2 = 0 + 20 Combine like terms: 0 + 20 = 20 8x + x2 = 20 The x term is 8x. Take half its coefficient (4). Square it (16) and add it to both sides. Add '16' to each side of the equation. 8x + 16 + x2 = 20 + 16 Reorder the terms: 16 + 8x + x2 = 20 + 16 Combine like terms: 20 + 16 = 36 16 + 8x + x2 = 36 Factor a perfect square on the left side: (x + 4)(x + 4) = 36 Calculate the square root of the right side: 6 Break this problem into two subproblems by setting (x + 4) equal to 6 and -6.Subproblem 1
x + 4 = 6 Simplifying x + 4 = 6 Reorder the terms: 4 + x = 6 Solving 4 + x = 6 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-4' to each side of the equation. 4 + -4 + x = 6 + -4 Combine like terms: 4 + -4 = 0 0 + x = 6 + -4 x = 6 + -4 Combine like terms: 6 + -4 = 2 x = 2 Simplifying x = 2Subproblem 2
x + 4 = -6 Simplifying x + 4 = -6 Reorder the terms: 4 + x = -6 Solving 4 + x = -6 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-4' to each side of the equation. 4 + -4 + x = -6 + -4 Combine like terms: 4 + -4 = 0 0 + x = -6 + -4 x = -6 + -4 Combine like terms: -6 + -4 = -10 x = -10 Simplifying x = -10Solution
The solution to the problem is based on the solutions from the subproblems. x = {2, -10}
