Simplifying x(2x) + 3x = 210 Remove parenthesis around (2x) x * 2x + 3x = 210 Reorder the terms for easier multiplication: 2x * x + 3x = 210 Multiply x * x 2x2 + 3x = 210 Reorder the terms: 3x + 2x2 = 210 Solving 3x + 2x2 = 210 Solving for variable 'x'. Reorder the terms: -210 + 3x + 2x2 = 210 + -210 Combine like terms: 210 + -210 = 0 -210 + 3x + 2x2 = 0 Begin completing the square. Divide all terms by 2 the coefficient of the squared term: Divide each side by '2'. -105 + 1.5x + x2 = 0 Move the constant term to the right: Add '105' to each side of the equation. -105 + 1.5x + 105 + x2 = 0 + 105 Reorder the terms: -105 + 105 + 1.5x + x2 = 0 + 105 Combine like terms: -105 + 105 = 0 0 + 1.5x + x2 = 0 + 105 1.5x + x2 = 0 + 105 Combine like terms: 0 + 105 = 105 1.5x + x2 = 105 The x term is 1.5x. Take half its coefficient (0.75). Square it (0.5625) and add it to both sides. Add '0.5625' to each side of the equation. 1.5x + 0.5625 + x2 = 105 + 0.5625 Reorder the terms: 0.5625 + 1.5x + x2 = 105 + 0.5625 Combine like terms: 105 + 0.5625 = 105.5625 0.5625 + 1.5x + x2 = 105.5625 Factor a perfect square on the left side: (x + 0.75)(x + 0.75) = 105.5625 Calculate the square root of the right side: 10.274361294 Break this problem into two subproblems by setting (x + 0.75) equal to 10.274361294 and -10.274361294.Subproblem 1
x + 0.75 = 10.274361294 Simplifying x + 0.75 = 10.274361294 Reorder the terms: 0.75 + x = 10.274361294 Solving 0.75 + x = 10.274361294 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-0.75' to each side of the equation. 0.75 + -0.75 + x = 10.274361294 + -0.75 Combine like terms: 0.75 + -0.75 = 0.00 0.00 + x = 10.274361294 + -0.75 x = 10.274361294 + -0.75 Combine like terms: 10.274361294 + -0.75 = 9.524361294 x = 9.524361294 Simplifying x = 9.524361294Subproblem 2
x + 0.75 = -10.274361294 Simplifying x + 0.75 = -10.274361294 Reorder the terms: 0.75 + x = -10.274361294 Solving 0.75 + x = -10.274361294 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-0.75' to each side of the equation. 0.75 + -0.75 + x = -10.274361294 + -0.75 Combine like terms: 0.75 + -0.75 = 0.00 0.00 + x = -10.274361294 + -0.75 x = -10.274361294 + -0.75 Combine like terms: -10.274361294 + -0.75 = -11.024361294 x = -11.024361294 Simplifying x = -11.024361294Solution
The solution to the problem is based on the solutions from the subproblems. x = {9.524361294, -11.024361294}
