Simplifying (-2.5x + -20)(x + -2) = 0 Reorder the terms: (-20 + -2.5x)(x + -2) = 0 Reorder the terms: (-20 + -2.5x)(-2 + x) = 0 Multiply (-20 + -2.5x) * (-2 + x) (-20(-2 + x) + -2.5x * (-2 + x)) = 0 ((-2 * -20 + x * -20) + -2.5x * (-2 + x)) = 0 ((40 + -20x) + -2.5x * (-2 + x)) = 0 (40 + -20x + (-2 * -2.5x + x * -2.5x)) = 0 (40 + -20x + (5x + -2.5x2)) = 0 Combine like terms: -20x + 5x = -15x (40 + -15x + -2.5x2) = 0 Solving 40 + -15x + -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'. -16 + 6x + x2 = 0 Move the constant term to the right: Add '16' to each side of the equation. -16 + 6x + 16 + x2 = 0 + 16 Reorder the terms: -16 + 16 + 6x + x2 = 0 + 16 Combine like terms: -16 + 16 = 0 0 + 6x + x2 = 0 + 16 6x + x2 = 0 + 16 Combine like terms: 0 + 16 = 16 6x + x2 = 16 The x term is 6x. Take half its coefficient (3). Square it (9) and add it to both sides. Add '9' to each side of the equation. 6x + 9 + x2 = 16 + 9 Reorder the terms: 9 + 6x + x2 = 16 + 9 Combine like terms: 16 + 9 = 25 9 + 6x + x2 = 25 Factor a perfect square on the left side: (x + 3)(x + 3) = 25 Calculate the square root of the right side: 5 Break this problem into two subproblems by setting (x + 3) equal to 5 and -5.Subproblem 1
x + 3 = 5 Simplifying x + 3 = 5 Reorder the terms: 3 + x = 5 Solving 3 + x = 5 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-3' to each side of the equation. 3 + -3 + x = 5 + -3 Combine like terms: 3 + -3 = 0 0 + x = 5 + -3 x = 5 + -3 Combine like terms: 5 + -3 = 2 x = 2 Simplifying x = 2Subproblem 2
x + 3 = -5 Simplifying x + 3 = -5 Reorder the terms: 3 + x = -5 Solving 3 + x = -5 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-3' to each side of the equation. 3 + -3 + x = -5 + -3 Combine like terms: 3 + -3 = 0 0 + x = -5 + -3 x = -5 + -3 Combine like terms: -5 + -3 = -8 x = -8 Simplifying x = -8Solution
The solution to the problem is based on the solutions from the subproblems. x = {2, -8}
