Simplifying 2.5x(x + 2) + 4.5 + 1.5(x + -3) = 15 Reorder the terms: 2.5x(2 + x) + 4.5 + 1.5(x + -3) = 15 (2 * 2.5x + x * 2.5x) + 4.5 + 1.5(x + -3) = 15 (5x + 2.5x2) + 4.5 + 1.5(x + -3) = 15 Reorder the terms: 5x + 2.5x2 + 4.5 + 1.5(-3 + x) = 15 5x + 2.5x2 + 4.5 + (-3 * 1.5 + x * 1.5) = 15 5x + 2.5x2 + 4.5 + (-4.5 + 1.5x) = 15 Reorder the terms: 4.5 + -4.5 + 5x + 1.5x + 2.5x2 = 15 Combine like terms: 4.5 + -4.5 = 0.0 0.0 + 5x + 1.5x + 2.5x2 = 15 5x + 1.5x + 2.5x2 = 15 Combine like terms: 5x + 1.5x = 6.5x 6.5x + 2.5x2 = 15 Solving 6.5x + 2.5x2 = 15 Solving for variable 'x'. Reorder the terms: -15 + 6.5x + 2.5x2 = 15 + -15 Combine like terms: 15 + -15 = 0 -15 + 6.5x + 2.5x2 = 0 Begin completing the square. Divide all terms by 2.5 the coefficient of the squared term: Divide each side by '2.5'. -6 + 2.6x + x2 = 0 Move the constant term to the right: Add '6' to each side of the equation. -6 + 2.6x + 6 + x2 = 0 + 6 Reorder the terms: -6 + 6 + 2.6x + x2 = 0 + 6 Combine like terms: -6 + 6 = 0 0 + 2.6x + x2 = 0 + 6 2.6x + x2 = 0 + 6 Combine like terms: 0 + 6 = 6 2.6x + x2 = 6 The x term is 2.6x. Take half its coefficient (1.3). Square it (1.69) and add it to both sides. Add '1.69' to each side of the equation. 2.6x + 1.69 + x2 = 6 + 1.69 Reorder the terms: 1.69 + 2.6x + x2 = 6 + 1.69 Combine like terms: 6 + 1.69 = 7.69 1.69 + 2.6x + x2 = 7.69 Factor a perfect square on the left side: (x + 1.3)(x + 1.3) = 7.69 Calculate the square root of the right side: 2.773084925 Break this problem into two subproblems by setting (x + 1.3) equal to 2.773084925 and -2.773084925.Subproblem 1
x + 1.3 = 2.773084925 Simplifying x + 1.3 = 2.773084925 Reorder the terms: 1.3 + x = 2.773084925 Solving 1.3 + x = 2.773084925 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-1.3' to each side of the equation. 1.3 + -1.3 + x = 2.773084925 + -1.3 Combine like terms: 1.3 + -1.3 = 0.0 0.0 + x = 2.773084925 + -1.3 x = 2.773084925 + -1.3 Combine like terms: 2.773084925 + -1.3 = 1.473084925 x = 1.473084925 Simplifying x = 1.473084925Subproblem 2
x + 1.3 = -2.773084925 Simplifying x + 1.3 = -2.773084925 Reorder the terms: 1.3 + x = -2.773084925 Solving 1.3 + x = -2.773084925 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-1.3' to each side of the equation. 1.3 + -1.3 + x = -2.773084925 + -1.3 Combine like terms: 1.3 + -1.3 = 0.0 0.0 + x = -2.773084925 + -1.3 x = -2.773084925 + -1.3 Combine like terms: -2.773084925 + -1.3 = -4.073084925 x = -4.073084925 Simplifying x = -4.073084925Solution
The solution to the problem is based on the solutions from the subproblems. x = {1.473084925, -4.073084925}
