Simplifying 3 + -5x2 + 4x = 0 Reorder the terms: 3 + 4x + -5x2 = 0 Solving 3 + 4x + -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 + -0.8x + x2 = 0 Move the constant term to the right: Add '0.6' to each side of the equation. -0.6 + -0.8x + 0.6 + x2 = 0 + 0.6 Reorder the terms: -0.6 + 0.6 + -0.8x + x2 = 0 + 0.6 Combine like terms: -0.6 + 0.6 = 0.0 0.0 + -0.8x + x2 = 0 + 0.6 -0.8x + x2 = 0 + 0.6 Combine like terms: 0 + 0.6 = 0.6 -0.8x + x2 = 0.6 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 = 0.6 + 0.16 Reorder the terms: 0.16 + -0.8x + x2 = 0.6 + 0.16 Combine like terms: 0.6 + 0.16 = 0.76 0.16 + -0.8x + x2 = 0.76 Factor a perfect square on the left side: (x + -0.4)(x + -0.4) = 0.76 Calculate the square root of the right side: 0.871779789 Break this problem into two subproblems by setting (x + -0.4) equal to 0.871779789 and -0.871779789.Subproblem 1
x + -0.4 = 0.871779789 Simplifying x + -0.4 = 0.871779789 Reorder the terms: -0.4 + x = 0.871779789 Solving -0.4 + x = 0.871779789 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 = 0.871779789 + 0.4 Combine like terms: -0.4 + 0.4 = 0.0 0.0 + x = 0.871779789 + 0.4 x = 0.871779789 + 0.4 Combine like terms: 0.871779789 + 0.4 = 1.271779789 x = 1.271779789 Simplifying x = 1.271779789Subproblem 2
x + -0.4 = -0.871779789 Simplifying x + -0.4 = -0.871779789 Reorder the terms: -0.4 + x = -0.871779789 Solving -0.4 + x = -0.871779789 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 = -0.871779789 + 0.4 Combine like terms: -0.4 + 0.4 = 0.0 0.0 + x = -0.871779789 + 0.4 x = -0.871779789 + 0.4 Combine like terms: -0.871779789 + 0.4 = -0.471779789 x = -0.471779789 Simplifying x = -0.471779789Solution
