Simplifying 105 + -28x = 10x2 Solving 105 + -28x = 10x2 Solving for variable 'x'. Combine like terms: 10x2 + -10x2 = 0 105 + -28x + -10x2 = 0 Begin completing the square. Divide all terms by -10 the coefficient of the squared term: Divide each side by '-10'. -10.5 + 2.8x + x2 = 0 Move the constant term to the right: Add '10.5' to each side of the equation. -10.5 + 2.8x + 10.5 + x2 = 0 + 10.5 Reorder the terms: -10.5 + 10.5 + 2.8x + x2 = 0 + 10.5 Combine like terms: -10.5 + 10.5 = 0.0 0.0 + 2.8x + x2 = 0 + 10.5 2.8x + x2 = 0 + 10.5 Combine like terms: 0 + 10.5 = 10.5 2.8x + x2 = 10.5 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 = 10.5 + 1.96 Reorder the terms: 1.96 + 2.8x + x2 = 10.5 + 1.96 Combine like terms: 10.5 + 1.96 = 12.46 1.96 + 2.8x + x2 = 12.46 Factor a perfect square on the left side: (x + 1.4)(x + 1.4) = 12.46 Calculate the square root of the right side: 3.529872519 Break this problem into two subproblems by setting (x + 1.4) equal to 3.529872519 and -3.529872519.Subproblem 1
x + 1.4 = 3.529872519 Simplifying x + 1.4 = 3.529872519 Reorder the terms: 1.4 + x = 3.529872519 Solving 1.4 + x = 3.529872519 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 = 3.529872519 + -1.4 Combine like terms: 1.4 + -1.4 = 0.0 0.0 + x = 3.529872519 + -1.4 x = 3.529872519 + -1.4 Combine like terms: 3.529872519 + -1.4 = 2.129872519 x = 2.129872519 Simplifying x = 2.129872519Subproblem 2
x + 1.4 = -3.529872519 Simplifying x + 1.4 = -3.529872519 Reorder the terms: 1.4 + x = -3.529872519 Solving 1.4 + x = -3.529872519 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 = -3.529872519 + -1.4 Combine like terms: 1.4 + -1.4 = 0.0 0.0 + x = -3.529872519 + -1.4 x = -3.529872519 + -1.4 Combine like terms: -3.529872519 + -1.4 = -4.929872519 x = -4.929872519 Simplifying x = -4.929872519Solution
The solution to the problem is based on the solutions from the subproblems. x = {2.129872519, -4.929872519}
