Simplifying 2.5x2 + 1.5x + -5 = 0 Reorder the terms: -5 + 1.5x + 2.5x2 = 0 Solving -5 + 1.5x + 2.5x2 = 0 Solving for variable 'x'. Begin completing the square. Divide all terms by 2.5 the coefficient of the squared term: Divide each side by '2.5'. -2 + 0.6x + x2 = 0 Move the constant term to the right: Add '2' to each side of the equation. -2 + 0.6x + 2 + x2 = 0 + 2 Reorder the terms: -2 + 2 + 0.6x + x2 = 0 + 2 Combine like terms: -2 + 2 = 0 0 + 0.6x + x2 = 0 + 2 0.6x + x2 = 0 + 2 Combine like terms: 0 + 2 = 2 0.6x + x2 = 2 The x term is 0.6x. Take half its coefficient (0.3). Square it (0.09) and add it to both sides. Add '0.09' to each side of the equation. 0.6x + 0.09 + x2 = 2 + 0.09 Reorder the terms: 0.09 + 0.6x + x2 = 2 + 0.09 Combine like terms: 2 + 0.09 = 2.09 0.09 + 0.6x + x2 = 2.09 Factor a perfect square on the left side: (x + 0.3)(x + 0.3) = 2.09 Calculate the square root of the right side: 1.445683229 Break this problem into two subproblems by setting (x + 0.3) equal to 1.445683229 and -1.445683229.Subproblem 1
x + 0.3 = 1.445683229 Simplifying x + 0.3 = 1.445683229 Reorder the terms: 0.3 + x = 1.445683229 Solving 0.3 + x = 1.445683229 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-0.3' to each side of the equation. 0.3 + -0.3 + x = 1.445683229 + -0.3 Combine like terms: 0.3 + -0.3 = 0.0 0.0 + x = 1.445683229 + -0.3 x = 1.445683229 + -0.3 Combine like terms: 1.445683229 + -0.3 = 1.145683229 x = 1.145683229 Simplifying x = 1.145683229Subproblem 2
x + 0.3 = -1.445683229 Simplifying x + 0.3 = -1.445683229 Reorder the terms: 0.3 + x = -1.445683229 Solving 0.3 + x = -1.445683229 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-0.3' to each side of the equation. 0.3 + -0.3 + x = -1.445683229 + -0.3 Combine like terms: 0.3 + -0.3 = 0.0 0.0 + x = -1.445683229 + -0.3 x = -1.445683229 + -0.3 Combine like terms: -1.445683229 + -0.3 = -1.745683229 x = -1.745683229 Simplifying x = -1.745683229Solution
The solution to the problem is based on the solutions from the subproblems. x = {1.145683229, -1.745683229}
