Simplifying -15x2 = 12x + -5 Reorder the terms: -15x2 = -5 + 12x Solving -15x2 = -5 + 12x Solving for variable 'x'. Reorder the terms: 5 + -12x + -15x2 = -5 + 12x + 5 + -12x Reorder the terms: 5 + -12x + -15x2 = -5 + 5 + 12x + -12x Combine like terms: -5 + 5 = 0 5 + -12x + -15x2 = 0 + 12x + -12x 5 + -12x + -15x2 = 12x + -12x Combine like terms: 12x + -12x = 0 5 + -12x + -15x2 = 0 Begin completing the square. Divide all terms by -15 the coefficient of the squared term: Divide each side by '-15'. -0.3333333333 + 0.8x + x2 = 0 Move the constant term to the right: Add '0.3333333333' to each side of the equation. -0.3333333333 + 0.8x + 0.3333333333 + x2 = 0 + 0.3333333333 Reorder the terms: -0.3333333333 + 0.3333333333 + 0.8x + x2 = 0 + 0.3333333333 Combine like terms: -0.3333333333 + 0.3333333333 = 0.0000000000 0.0000000000 + 0.8x + x2 = 0 + 0.3333333333 0.8x + x2 = 0 + 0.3333333333 Combine like terms: 0 + 0.3333333333 = 0.3333333333 0.8x + x2 = 0.3333333333 The x term is 0.8x. Take half its coefficient (0.4). Square it (0.16) and add it to both sides. Add '0.16' to each side of the equation. 0.8x + 0.16 + x2 = 0.3333333333 + 0.16 Reorder the terms: 0.16 + 0.8x + x2 = 0.3333333333 + 0.16 Combine like terms: 0.3333333333 + 0.16 = 0.4933333333 0.16 + 0.8x + x2 = 0.4933333333 Factor a perfect square on the left side: (x + 0.4)(x + 0.4) = 0.4933333333 Calculate the square root of the right side: 0.702376917 Break this problem into two subproblems by setting (x + 0.4) equal to 0.702376917 and -0.702376917.Subproblem 1
x + 0.4 = 0.702376917 Simplifying x + 0.4 = 0.702376917 Reorder the terms: 0.4 + x = 0.702376917 Solving 0.4 + x = 0.702376917 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-0.4' to each side of the equation. 0.4 + -0.4 + x = 0.702376917 + -0.4 Combine like terms: 0.4 + -0.4 = 0.0 0.0 + x = 0.702376917 + -0.4 x = 0.702376917 + -0.4 Combine like terms: 0.702376917 + -0.4 = 0.302376917 x = 0.302376917 Simplifying x = 0.302376917Subproblem 2
x + 0.4 = -0.702376917 Simplifying x + 0.4 = -0.702376917 Reorder the terms: 0.4 + x = -0.702376917 Solving 0.4 + x = -0.702376917 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-0.4' to each side of the equation. 0.4 + -0.4 + x = -0.702376917 + -0.4 Combine like terms: 0.4 + -0.4 = 0.0 0.0 + x = -0.702376917 + -0.4 x = -0.702376917 + -0.4 Combine like terms: -0.702376917 + -0.4 = -1.102376917 x = -1.102376917 Simplifying x = -1.102376917Solution
