Simplifying 5x2 + -18x + -4 = 0 Reorder the terms: -4 + -18x + 5x2 = 0 Solving -4 + -18x + 5x2 = 0 Solving for variable 'x'. Begin completing the square. Divide all terms by 5 the coefficient of the squared term: Divide each side by '5'. -0.8 + -3.6x + x2 = 0 Move the constant term to the right: Add '0.8' to each side of the equation. -0.8 + -3.6x + 0.8 + x2 = 0 + 0.8 Reorder the terms: -0.8 + 0.8 + -3.6x + x2 = 0 + 0.8 Combine like terms: -0.8 + 0.8 = 0.0 0.0 + -3.6x + x2 = 0 + 0.8 -3.6x + x2 = 0 + 0.8 Combine like terms: 0 + 0.8 = 0.8 -3.6x + x2 = 0.8 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 = 0.8 + 3.24 Reorder the terms: 3.24 + -3.6x + x2 = 0.8 + 3.24 Combine like terms: 0.8 + 3.24 = 4.04 3.24 + -3.6x + x2 = 4.04 Factor a perfect square on the left side: (x + -1.8)(x + -1.8) = 4.04 Calculate the square root of the right side: 2.009975124 Break this problem into two subproblems by setting (x + -1.8) equal to 2.009975124 and -2.009975124.Subproblem 1
x + -1.8 = 2.009975124 Simplifying x + -1.8 = 2.009975124 Reorder the terms: -1.8 + x = 2.009975124 Solving -1.8 + x = 2.009975124 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 = 2.009975124 + 1.8 Combine like terms: -1.8 + 1.8 = 0.0 0.0 + x = 2.009975124 + 1.8 x = 2.009975124 + 1.8 Combine like terms: 2.009975124 + 1.8 = 3.809975124 x = 3.809975124 Simplifying x = 3.809975124Subproblem 2
x + -1.8 = -2.009975124 Simplifying x + -1.8 = -2.009975124 Reorder the terms: -1.8 + x = -2.009975124 Solving -1.8 + x = -2.009975124 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 = -2.009975124 + 1.8 Combine like terms: -1.8 + 1.8 = 0.0 0.0 + x = -2.009975124 + 1.8 x = -2.009975124 + 1.8 Combine like terms: -2.009975124 + 1.8 = -0.209975124 x = -0.209975124 Simplifying x = -0.209975124Solution
