Simplifying 58.8 = 4.9x2 + 34.3x + 0 Reorder the terms: 58.8 = 0 + 34.3x + 4.9x2 Remove the zero: 58.8 = 34.3x + 4.9x2 Solving 58.8 = 34.3x + 4.9x2 Solving for variable 'x'. Reorder the terms: 58.8 + -34.3x + -4.9x2 = 34.3x + -34.3x + 4.9x2 + -4.9x2 Combine like terms: 34.3x + -34.3x = 0.0 58.8 + -34.3x + -4.9x2 = 0.0 + 4.9x2 + -4.9x2 58.8 + -34.3x + -4.9x2 = 4.9x2 + -4.9x2 Combine like terms: 4.9x2 + -4.9x2 = 0.0 58.8 + -34.3x + -4.9x2 = 0.0 Begin completing the square. Divide all terms by -4.9 the coefficient of the squared term: Divide each side by '-4.9'. -12 + 7x + x2 = 0 Move the constant term to the right: Add '12' to each side of the equation. -12 + 7x + 12 + x2 = 0 + 12 Reorder the terms: -12 + 12 + 7x + x2 = 0 + 12 Combine like terms: -12 + 12 = 0 0 + 7x + x2 = 0 + 12 7x + x2 = 0 + 12 Combine like terms: 0 + 12 = 12 7x + x2 = 12 The x term is 7x. Take half its coefficient (3.5). Square it (12.25) and add it to both sides. Add '12.25' to each side of the equation. 7x + 12.25 + x2 = 12 + 12.25 Reorder the terms: 12.25 + 7x + x2 = 12 + 12.25 Combine like terms: 12 + 12.25 = 24.25 12.25 + 7x + x2 = 24.25 Factor a perfect square on the left side: (x + 3.5)(x + 3.5) = 24.25 Calculate the square root of the right side: 4.924428901 Break this problem into two subproblems by setting (x + 3.5) equal to 4.924428901 and -4.924428901.Subproblem 1
x + 3.5 = 4.924428901 Simplifying x + 3.5 = 4.924428901 Reorder the terms: 3.5 + x = 4.924428901 Solving 3.5 + x = 4.924428901 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-3.5' to each side of the equation. 3.5 + -3.5 + x = 4.924428901 + -3.5 Combine like terms: 3.5 + -3.5 = 0.0 0.0 + x = 4.924428901 + -3.5 x = 4.924428901 + -3.5 Combine like terms: 4.924428901 + -3.5 = 1.424428901 x = 1.424428901 Simplifying x = 1.424428901Subproblem 2
x + 3.5 = -4.924428901 Simplifying x + 3.5 = -4.924428901 Reorder the terms: 3.5 + x = -4.924428901 Solving 3.5 + x = -4.924428901 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-3.5' to each side of the equation. 3.5 + -3.5 + x = -4.924428901 + -3.5 Combine like terms: 3.5 + -3.5 = 0.0 0.0 + x = -4.924428901 + -3.5 x = -4.924428901 + -3.5 Combine like terms: -4.924428901 + -3.5 = -8.424428901 x = -8.424428901 Simplifying x = -8.424428901Solution
The solution to the problem is based on the solutions from the subproblems. x = {1.424428901, -8.424428901}
