Simplifying 25x2 + 30x + -18 = 0 Reorder the terms: -18 + 30x + 25x2 = 0 Solving -18 + 30x + 25x2 = 0 Solving for variable 'x'. Begin completing the square. Divide all terms by 25 the coefficient of the squared term: Divide each side by '25'. -0.72 + 1.2x + x2 = 0 Move the constant term to the right: Add '0.72' to each side of the equation. -0.72 + 1.2x + 0.72 + x2 = 0 + 0.72 Reorder the terms: -0.72 + 0.72 + 1.2x + x2 = 0 + 0.72 Combine like terms: -0.72 + 0.72 = 0.00 0.00 + 1.2x + x2 = 0 + 0.72 1.2x + x2 = 0 + 0.72 Combine like terms: 0 + 0.72 = 0.72 1.2x + x2 = 0.72 The x term is 1.2x. Take half its coefficient (0.6). Square it (0.36) and add it to both sides. Add '0.36' to each side of the equation. 1.2x + 0.36 + x2 = 0.72 + 0.36 Reorder the terms: 0.36 + 1.2x + x2 = 0.72 + 0.36 Combine like terms: 0.72 + 0.36 = 1.08 0.36 + 1.2x + x2 = 1.08 Factor a perfect square on the left side: (x + 0.6)(x + 0.6) = 1.08 Calculate the square root of the right side: 1.039230485 Break this problem into two subproblems by setting (x + 0.6) equal to 1.039230485 and -1.039230485.Subproblem 1
x + 0.6 = 1.039230485 Simplifying x + 0.6 = 1.039230485 Reorder the terms: 0.6 + x = 1.039230485 Solving 0.6 + x = 1.039230485 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-0.6' to each side of the equation. 0.6 + -0.6 + x = 1.039230485 + -0.6 Combine like terms: 0.6 + -0.6 = 0.0 0.0 + x = 1.039230485 + -0.6 x = 1.039230485 + -0.6 Combine like terms: 1.039230485 + -0.6 = 0.439230485 x = 0.439230485 Simplifying x = 0.439230485Subproblem 2
x + 0.6 = -1.039230485 Simplifying x + 0.6 = -1.039230485 Reorder the terms: 0.6 + x = -1.039230485 Solving 0.6 + x = -1.039230485 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-0.6' to each side of the equation. 0.6 + -0.6 + x = -1.039230485 + -0.6 Combine like terms: 0.6 + -0.6 = 0.0 0.0 + x = -1.039230485 + -0.6 x = -1.039230485 + -0.6 Combine like terms: -1.039230485 + -0.6 = -1.639230485 x = -1.639230485 Simplifying x = -1.639230485Solution
The solution to the problem is based on the solutions from the subproblems. x = {0.439230485, -1.639230485}
