Simplifying x2 + -4.8 * 0.01 + 4.8x = 0 Multiply -4.8 * 0.01 x2 + -0.048 + 4.8x = 0 Reorder the terms: -0.048 + 4.8x + x2 = 0 Solving -0.048 + 4.8x + x2 = 0 Solving for variable 'x'. Begin completing the square. Move the constant term to the right: Add '0.048' to each side of the equation. -0.048 + 4.8x + 0.048 + x2 = 0 + 0.048 Reorder the terms: -0.048 + 0.048 + 4.8x + x2 = 0 + 0.048 Combine like terms: -0.048 + 0.048 = 0.000 0.000 + 4.8x + x2 = 0 + 0.048 4.8x + x2 = 0 + 0.048 Combine like terms: 0 + 0.048 = 0.048 4.8x + x2 = 0.048 The x term is 4.8x. Take half its coefficient (2.4). Square it (5.76) and add it to both sides. Add '5.76' to each side of the equation. 4.8x + 5.76 + x2 = 0.048 + 5.76 Reorder the terms: 5.76 + 4.8x + x2 = 0.048 + 5.76 Combine like terms: 0.048 + 5.76 = 5.808 5.76 + 4.8x + x2 = 5.808 Factor a perfect square on the left side: (x + 2.4)(x + 2.4) = 5.808 Calculate the square root of the right side: 2.409979253 Break this problem into two subproblems by setting (x + 2.4) equal to 2.409979253 and -2.409979253.Subproblem 1
x + 2.4 = 2.409979253 Simplifying x + 2.4 = 2.409979253 Reorder the terms: 2.4 + x = 2.409979253 Solving 2.4 + x = 2.409979253 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-2.4' to each side of the equation. 2.4 + -2.4 + x = 2.409979253 + -2.4 Combine like terms: 2.4 + -2.4 = 0.0 0.0 + x = 2.409979253 + -2.4 x = 2.409979253 + -2.4 Combine like terms: 2.409979253 + -2.4 = 0.009979253 x = 0.009979253 Simplifying x = 0.009979253Subproblem 2
x + 2.4 = -2.409979253 Simplifying x + 2.4 = -2.409979253 Reorder the terms: 2.4 + x = -2.409979253 Solving 2.4 + x = -2.409979253 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-2.4' to each side of the equation. 2.4 + -2.4 + x = -2.409979253 + -2.4 Combine like terms: 2.4 + -2.4 = 0.0 0.0 + x = -2.409979253 + -2.4 x = -2.409979253 + -2.4 Combine like terms: -2.409979253 + -2.4 = -4.809979253 x = -4.809979253 Simplifying x = -4.809979253Solution
The solution to the problem is based on the solutions from the subproblems. x = {0.009979253, -4.809979253}
