Simplifying 5x2 + 18x + -180 = 0 Reorder the terms: -180 + 18x + 5x2 = 0 Solving -180 + 18x + 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'. -36 + 3.6x + x2 = 0 Move the constant term to the right: Add '36' to each side of the equation. -36 + 3.6x + 36 + x2 = 0 + 36 Reorder the terms: -36 + 36 + 3.6x + x2 = 0 + 36 Combine like terms: -36 + 36 = 0 0 + 3.6x + x2 = 0 + 36 3.6x + x2 = 0 + 36 Combine like terms: 0 + 36 = 36 3.6x + x2 = 36 The x term is 3.6x. Take half its coefficient (1.8). Square it (3.24) and add it to both sides. Add '3.24' to each side of the equation. 3.6x + 3.24 + x2 = 36 + 3.24 Reorder the terms: 3.24 + 3.6x + x2 = 36 + 3.24 Combine like terms: 36 + 3.24 = 39.24 3.24 + 3.6x + x2 = 39.24 Factor a perfect square on the left side: (x + 1.8)(x + 1.8) = 39.24 Calculate the square root of the right side: 6.264183905 Break this problem into two subproblems by setting (x + 1.8) equal to 6.264183905 and -6.264183905.Subproblem 1
x + 1.8 = 6.264183905 Simplifying x + 1.8 = 6.264183905 Reorder the terms: 1.8 + x = 6.264183905 Solving 1.8 + x = 6.264183905 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-1.8' to each side of the equation. 1.8 + -1.8 + x = 6.264183905 + -1.8 Combine like terms: 1.8 + -1.8 = 0.0 0.0 + x = 6.264183905 + -1.8 x = 6.264183905 + -1.8 Combine like terms: 6.264183905 + -1.8 = 4.464183905 x = 4.464183905 Simplifying x = 4.464183905Subproblem 2
x + 1.8 = -6.264183905 Simplifying x + 1.8 = -6.264183905 Reorder the terms: 1.8 + x = -6.264183905 Solving 1.8 + x = -6.264183905 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-1.8' to each side of the equation. 1.8 + -1.8 + x = -6.264183905 + -1.8 Combine like terms: 1.8 + -1.8 = 0.0 0.0 + x = -6.264183905 + -1.8 x = -6.264183905 + -1.8 Combine like terms: -6.264183905 + -1.8 = -8.064183905 x = -8.064183905 Simplifying x = -8.064183905Solution
The solution to the problem is based on the solutions from the subproblems. x = {4.464183905, -8.064183905}
