Simplifying 10x2 + 30x + 21 = 0 Reorder the terms: 21 + 30x + 10x2 = 0 Solving 21 + 30x + 10x2 = 0 Solving for variable 'x'. Begin completing the square. Divide all terms by 10 the coefficient of the squared term: Divide each side by '10'. 2.1 + 3x + x2 = 0 Move the constant term to the right: Add '-2.1' to each side of the equation. 2.1 + 3x + -2.1 + x2 = 0 + -2.1 Reorder the terms: 2.1 + -2.1 + 3x + x2 = 0 + -2.1 Combine like terms: 2.1 + -2.1 = 0.0 0.0 + 3x + x2 = 0 + -2.1 3x + x2 = 0 + -2.1 Combine like terms: 0 + -2.1 = -2.1 3x + x2 = -2.1 The x term is 3x. Take half its coefficient (1.5). Square it (2.25) and add it to both sides. Add '2.25' to each side of the equation. 3x + 2.25 + x2 = -2.1 + 2.25 Reorder the terms: 2.25 + 3x + x2 = -2.1 + 2.25 Combine like terms: -2.1 + 2.25 = 0.15 2.25 + 3x + x2 = 0.15 Factor a perfect square on the left side: (x + 1.5)(x + 1.5) = 0.15 Calculate the square root of the right side: 0.387298335 Break this problem into two subproblems by setting (x + 1.5) equal to 0.387298335 and -0.387298335.Subproblem 1
x + 1.5 = 0.387298335 Simplifying x + 1.5 = 0.387298335 Reorder the terms: 1.5 + x = 0.387298335 Solving 1.5 + x = 0.387298335 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-1.5' to each side of the equation. 1.5 + -1.5 + x = 0.387298335 + -1.5 Combine like terms: 1.5 + -1.5 = 0.0 0.0 + x = 0.387298335 + -1.5 x = 0.387298335 + -1.5 Combine like terms: 0.387298335 + -1.5 = -1.112701665 x = -1.112701665 Simplifying x = -1.112701665Subproblem 2
x + 1.5 = -0.387298335 Simplifying x + 1.5 = -0.387298335 Reorder the terms: 1.5 + x = -0.387298335 Solving 1.5 + x = -0.387298335 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-1.5' to each side of the equation. 1.5 + -1.5 + x = -0.387298335 + -1.5 Combine like terms: 1.5 + -1.5 = 0.0 0.0 + x = -0.387298335 + -1.5 x = -0.387298335 + -1.5 Combine like terms: -0.387298335 + -1.5 = -1.887298335 x = -1.887298335 Simplifying x = -1.887298335Solution
The solution to the problem is based on the solutions from the subproblems. x = {-1.112701665, -1.887298335}
