Simplifying 10x2 + 28x + -1 = 0 Reorder the terms: -1 + 28x + 10x2 = 0 Solving -1 + 28x + 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'. -0.1 + 2.8x + x2 = 0 Move the constant term to the right: Add '0.1' to each side of the equation. -0.1 + 2.8x + 0.1 + x2 = 0 + 0.1 Reorder the terms: -0.1 + 0.1 + 2.8x + x2 = 0 + 0.1 Combine like terms: -0.1 + 0.1 = 0.0 0.0 + 2.8x + x2 = 0 + 0.1 2.8x + x2 = 0 + 0.1 Combine like terms: 0 + 0.1 = 0.1 2.8x + x2 = 0.1 The x term is 2.8x. Take half its coefficient (1.4). Square it (1.96) and add it to both sides. Add '1.96' to each side of the equation. 2.8x + 1.96 + x2 = 0.1 + 1.96 Reorder the terms: 1.96 + 2.8x + x2 = 0.1 + 1.96 Combine like terms: 0.1 + 1.96 = 2.06 1.96 + 2.8x + x2 = 2.06 Factor a perfect square on the left side: (x + 1.4)(x + 1.4) = 2.06 Calculate the square root of the right side: 1.435270009 Break this problem into two subproblems by setting (x + 1.4) equal to 1.435270009 and -1.435270009.Subproblem 1
x + 1.4 = 1.435270009 Simplifying x + 1.4 = 1.435270009 Reorder the terms: 1.4 + x = 1.435270009 Solving 1.4 + x = 1.435270009 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-1.4' to each side of the equation. 1.4 + -1.4 + x = 1.435270009 + -1.4 Combine like terms: 1.4 + -1.4 = 0.0 0.0 + x = 1.435270009 + -1.4 x = 1.435270009 + -1.4 Combine like terms: 1.435270009 + -1.4 = 0.035270009 x = 0.035270009 Simplifying x = 0.035270009Subproblem 2
x + 1.4 = -1.435270009 Simplifying x + 1.4 = -1.435270009 Reorder the terms: 1.4 + x = -1.435270009 Solving 1.4 + x = -1.435270009 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-1.4' to each side of the equation. 1.4 + -1.4 + x = -1.435270009 + -1.4 Combine like terms: 1.4 + -1.4 = 0.0 0.0 + x = -1.435270009 + -1.4 x = -1.435270009 + -1.4 Combine like terms: -1.435270009 + -1.4 = -2.835270009 x = -2.835270009 Simplifying x = -2.835270009Solution
The solution to the problem is based on the solutions from the subproblems. x = {0.035270009, -2.835270009}
