Simplifying (2x + 5)(x + -4) = x(x + -6) Reorder the terms: (5 + 2x)(x + -4) = x(x + -6) Reorder the terms: (5 + 2x)(-4 + x) = x(x + -6) Multiply (5 + 2x) * (-4 + x) (5(-4 + x) + 2x * (-4 + x)) = x(x + -6) ((-4 * 5 + x * 5) + 2x * (-4 + x)) = x(x + -6) ((-20 + 5x) + 2x * (-4 + x)) = x(x + -6) (-20 + 5x + (-4 * 2x + x * 2x)) = x(x + -6) (-20 + 5x + (-8x + 2x2)) = x(x + -6) Combine like terms: 5x + -8x = -3x (-20 + -3x + 2x2) = x(x + -6) Reorder the terms: -20 + -3x + 2x2 = x(-6 + x) -20 + -3x + 2x2 = (-6 * x + x * x) -20 + -3x + 2x2 = (-6x + x2) Solving -20 + -3x + 2x2 = -6x + x2 Solving for variable 'x'. Reorder the terms: -20 + -3x + 6x + 2x2 + -1x2 = -6x + x2 + 6x + -1x2 Combine like terms: -3x + 6x = 3x -20 + 3x + 2x2 + -1x2 = -6x + x2 + 6x + -1x2 Combine like terms: 2x2 + -1x2 = 1x2 -20 + 3x + 1x2 = -6x + x2 + 6x + -1x2 Reorder the terms: -20 + 3x + 1x2 = -6x + 6x + x2 + -1x2 Combine like terms: -6x + 6x = 0 -20 + 3x + 1x2 = 0 + x2 + -1x2 -20 + 3x + 1x2 = x2 + -1x2 Combine like terms: x2 + -1x2 = 0 -20 + 3x + 1x2 = 0 Begin completing the square. Move the constant term to the right: Add '20' to each side of the equation. -20 + 3x + 20 + x2 = 0 + 20 Reorder the terms: -20 + 20 + 3x + x2 = 0 + 20 Combine like terms: -20 + 20 = 0 0 + 3x + x2 = 0 + 20 3x + x2 = 0 + 20 Combine like terms: 0 + 20 = 20 3x + x2 = 20 The x term is 3x. Take half its coefficient (1.5). Square it (2.25) and add it to both sides. Add '2.25' to each side of the equation. 3x + 2.25 + x2 = 20 + 2.25 Reorder the terms: 2.25 + 3x + x2 = 20 + 2.25 Combine like terms: 20 + 2.25 = 22.25 2.25 + 3x + x2 = 22.25 Factor a perfect square on the left side: (x + 1.5)(x + 1.5) = 22.25 Calculate the square root of the right side: 4.716990566 Break this problem into two subproblems by setting (x + 1.5) equal to 4.716990566 and -4.716990566.Subproblem 1
x + 1.5 = 4.716990566 Simplifying x + 1.5 = 4.716990566 Reorder the terms: 1.5 + x = 4.716990566 Solving 1.5 + x = 4.716990566 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-1.5' to each side of the equation. 1.5 + -1.5 + x = 4.716990566 + -1.5 Combine like terms: 1.5 + -1.5 = 0.0 0.0 + x = 4.716990566 + -1.5 x = 4.716990566 + -1.5 Combine like terms: 4.716990566 + -1.5 = 3.216990566 x = 3.216990566 Simplifying x = 3.216990566Subproblem 2
x + 1.5 = -4.716990566 Simplifying x + 1.5 = -4.716990566 Reorder the terms: 1.5 + x = -4.716990566 Solving 1.5 + x = -4.716990566 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-1.5' to each side of the equation. 1.5 + -1.5 + x = -4.716990566 + -1.5 Combine like terms: 1.5 + -1.5 = 0.0 0.0 + x = -4.716990566 + -1.5 x = -4.716990566 + -1.5 Combine like terms: -4.716990566 + -1.5 = -6.216990566 x = -6.216990566 Simplifying x = -6.216990566Solution
The solution to the problem is based on the solutions from the subproblems. x = {3.216990566, -6.216990566}
