Simplifying 0.45x2 + -2.61x + 2.88 = 0 Reorder the terms: 2.88 + -2.61x + 0.45x2 = 0 Solving 2.88 + -2.61x + 0.45x2 = 0 Solving for variable 'x'. Begin completing the square. Divide all terms by 0.45 the coefficient of the squared term: Divide each side by '0.45'. 6.4 + -5.8x + x2 = 0 Move the constant term to the right: Add '-6.4' to each side of the equation. 6.4 + -5.8x + -6.4 + x2 = 0 + -6.4 Reorder the terms: 6.4 + -6.4 + -5.8x + x2 = 0 + -6.4 Combine like terms: 6.4 + -6.4 = 0.0 0.0 + -5.8x + x2 = 0 + -6.4 -5.8x + x2 = 0 + -6.4 Combine like terms: 0 + -6.4 = -6.4 -5.8x + x2 = -6.4 The x term is -5.8x. Take half its coefficient (-2.9). Square it (8.41) and add it to both sides. Add '8.41' to each side of the equation. -5.8x + 8.41 + x2 = -6.4 + 8.41 Reorder the terms: 8.41 + -5.8x + x2 = -6.4 + 8.41 Combine like terms: -6.4 + 8.41 = 2.01 8.41 + -5.8x + x2 = 2.01 Factor a perfect square on the left side: (x + -2.9)(x + -2.9) = 2.01 Calculate the square root of the right side: 1.417744688 Break this problem into two subproblems by setting (x + -2.9) equal to 1.417744688 and -1.417744688.Subproblem 1
x + -2.9 = 1.417744688 Simplifying x + -2.9 = 1.417744688 Reorder the terms: -2.9 + x = 1.417744688 Solving -2.9 + x = 1.417744688 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '2.9' to each side of the equation. -2.9 + 2.9 + x = 1.417744688 + 2.9 Combine like terms: -2.9 + 2.9 = 0.0 0.0 + x = 1.417744688 + 2.9 x = 1.417744688 + 2.9 Combine like terms: 1.417744688 + 2.9 = 4.317744688 x = 4.317744688 Simplifying x = 4.317744688Subproblem 2
x + -2.9 = -1.417744688 Simplifying x + -2.9 = -1.417744688 Reorder the terms: -2.9 + x = -1.417744688 Solving -2.9 + x = -1.417744688 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '2.9' to each side of the equation. -2.9 + 2.9 + x = -1.417744688 + 2.9 Combine like terms: -2.9 + 2.9 = 0.0 0.0 + x = -1.417744688 + 2.9 x = -1.417744688 + 2.9 Combine like terms: -1.417744688 + 2.9 = 1.482255312 x = 1.482255312 Simplifying x = 1.482255312Solution
