Simplifying 8x2 + -18x + -5 = 3x2 Reorder the terms: -5 + -18x + 8x2 = 3x2 Solving -5 + -18x + 8x2 = 3x2 Solving for variable 'x'. Combine like terms: 8x2 + -3x2 = 5x2 -5 + -18x + 5x2 = 3x2 + -3x2 Combine like terms: 3x2 + -3x2 = 0 -5 + -18x + 5x2 = 0 Begin completing the square. Divide all terms by 5 the coefficient of the squared term: Divide each side by '5'. -1 + -3.6x + x2 = 0 Move the constant term to the right: Add '1' to each side of the equation. -1 + -3.6x + 1 + x2 = 0 + 1 Reorder the terms: -1 + 1 + -3.6x + x2 = 0 + 1 Combine like terms: -1 + 1 = 0 0 + -3.6x + x2 = 0 + 1 -3.6x + x2 = 0 + 1 Combine like terms: 0 + 1 = 1 -3.6x + x2 = 1 The x term is -3.6x. Take half its coefficient (-1.8). Square it (3.24) and add it to both sides. Add '3.24' to each side of the equation. -3.6x + 3.24 + x2 = 1 + 3.24 Reorder the terms: 3.24 + -3.6x + x2 = 1 + 3.24 Combine like terms: 1 + 3.24 = 4.24 3.24 + -3.6x + x2 = 4.24 Factor a perfect square on the left side: (x + -1.8)(x + -1.8) = 4.24 Calculate the square root of the right side: 2.059126028 Break this problem into two subproblems by setting (x + -1.8) equal to 2.059126028 and -2.059126028.Subproblem 1
x + -1.8 = 2.059126028 Simplifying x + -1.8 = 2.059126028 Reorder the terms: -1.8 + x = 2.059126028 Solving -1.8 + x = 2.059126028 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '1.8' to each side of the equation. -1.8 + 1.8 + x = 2.059126028 + 1.8 Combine like terms: -1.8 + 1.8 = 0.0 0.0 + x = 2.059126028 + 1.8 x = 2.059126028 + 1.8 Combine like terms: 2.059126028 + 1.8 = 3.859126028 x = 3.859126028 Simplifying x = 3.859126028Subproblem 2
x + -1.8 = -2.059126028 Simplifying x + -1.8 = -2.059126028 Reorder the terms: -1.8 + x = -2.059126028 Solving -1.8 + x = -2.059126028 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '1.8' to each side of the equation. -1.8 + 1.8 + x = -2.059126028 + 1.8 Combine like terms: -1.8 + 1.8 = 0.0 0.0 + x = -2.059126028 + 1.8 x = -2.059126028 + 1.8 Combine like terms: -2.059126028 + 1.8 = -0.259126028 x = -0.259126028 Simplifying x = -0.259126028Solution
The solution to the problem is based on the solutions from the subproblems. x = {3.859126028, -0.259126028}
