Simplifying 0.5x2 + -1.2x + -7 = 0 Reorder the terms: -7 + -1.2x + 0.5x2 = 0 Solving -7 + -1.2x + 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'. -14 + -2.4x + x2 = 0 Move the constant term to the right: Add '14' to each side of the equation. -14 + -2.4x + 14 + x2 = 0 + 14 Reorder the terms: -14 + 14 + -2.4x + x2 = 0 + 14 Combine like terms: -14 + 14 = 0 0 + -2.4x + x2 = 0 + 14 -2.4x + x2 = 0 + 14 Combine like terms: 0 + 14 = 14 -2.4x + x2 = 14 The x term is -2.4x. Take half its coefficient (-1.2). Square it (1.44) and add it to both sides. Add '1.44' to each side of the equation. -2.4x + 1.44 + x2 = 14 + 1.44 Reorder the terms: 1.44 + -2.4x + x2 = 14 + 1.44 Combine like terms: 14 + 1.44 = 15.44 1.44 + -2.4x + x2 = 15.44 Factor a perfect square on the left side: (x + -1.2)(x + -1.2) = 15.44 Calculate the square root of the right side: 3.929376541 Break this problem into two subproblems by setting (x + -1.2) equal to 3.929376541 and -3.929376541.Subproblem 1
x + -1.2 = 3.929376541 Simplifying x + -1.2 = 3.929376541 Reorder the terms: -1.2 + x = 3.929376541 Solving -1.2 + x = 3.929376541 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '1.2' to each side of the equation. -1.2 + 1.2 + x = 3.929376541 + 1.2 Combine like terms: -1.2 + 1.2 = 0.0 0.0 + x = 3.929376541 + 1.2 x = 3.929376541 + 1.2 Combine like terms: 3.929376541 + 1.2 = 5.129376541 x = 5.129376541 Simplifying x = 5.129376541Subproblem 2
x + -1.2 = -3.929376541 Simplifying x + -1.2 = -3.929376541 Reorder the terms: -1.2 + x = -3.929376541 Solving -1.2 + x = -3.929376541 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '1.2' to each side of the equation. -1.2 + 1.2 + x = -3.929376541 + 1.2 Combine like terms: -1.2 + 1.2 = 0.0 0.0 + x = -3.929376541 + 1.2 x = -3.929376541 + 1.2 Combine like terms: -3.929376541 + 1.2 = -2.729376541 x = -2.729376541 Simplifying x = -2.729376541Solution
