Simplifying -5x2 + 9x + 3 = 0 Reorder the terms: 3 + 9x + -5x2 = 0 Solving 3 + 9x + -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'. -0.6 + -1.8x + x2 = 0 Move the constant term to the right: Add '0.6' to each side of the equation. -0.6 + -1.8x + 0.6 + x2 = 0 + 0.6 Reorder the terms: -0.6 + 0.6 + -1.8x + x2 = 0 + 0.6 Combine like terms: -0.6 + 0.6 = 0.0 0.0 + -1.8x + x2 = 0 + 0.6 -1.8x + x2 = 0 + 0.6 Combine like terms: 0 + 0.6 = 0.6 -1.8x + x2 = 0.6 The x term is -1.8x. Take half its coefficient (-0.9). Square it (0.81) and add it to both sides. Add '0.81' to each side of the equation. -1.8x + 0.81 + x2 = 0.6 + 0.81 Reorder the terms: 0.81 + -1.8x + x2 = 0.6 + 0.81 Combine like terms: 0.6 + 0.81 = 1.41 0.81 + -1.8x + x2 = 1.41 Factor a perfect square on the left side: (x + -0.9)(x + -0.9) = 1.41 Calculate the square root of the right side: 1.187434209 Break this problem into two subproblems by setting (x + -0.9) equal to 1.187434209 and -1.187434209.Subproblem 1
x + -0.9 = 1.187434209 Simplifying x + -0.9 = 1.187434209 Reorder the terms: -0.9 + x = 1.187434209 Solving -0.9 + x = 1.187434209 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '0.9' to each side of the equation. -0.9 + 0.9 + x = 1.187434209 + 0.9 Combine like terms: -0.9 + 0.9 = 0.0 0.0 + x = 1.187434209 + 0.9 x = 1.187434209 + 0.9 Combine like terms: 1.187434209 + 0.9 = 2.087434209 x = 2.087434209 Simplifying x = 2.087434209Subproblem 2
x + -0.9 = -1.187434209 Simplifying x + -0.9 = -1.187434209 Reorder the terms: -0.9 + x = -1.187434209 Solving -0.9 + x = -1.187434209 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '0.9' to each side of the equation. -0.9 + 0.9 + x = -1.187434209 + 0.9 Combine like terms: -0.9 + 0.9 = 0.0 0.0 + x = -1.187434209 + 0.9 x = -1.187434209 + 0.9 Combine like terms: -1.187434209 + 0.9 = -0.287434209 x = -0.287434209 Simplifying x = -0.287434209Solution
