Simplifying (x + 5) * 2 + -3x = (x + -5)(x + -5) Reorder the terms: (5 + x) * 2 + -3x = (x + -5)(x + -5) Reorder the terms for easier multiplication: 2(5 + x) + -3x = (x + -5)(x + -5) (5 * 2 + x * 2) + -3x = (x + -5)(x + -5) (10 + 2x) + -3x = (x + -5)(x + -5) Combine like terms: 2x + -3x = -1x 10 + -1x = (x + -5)(x + -5) Reorder the terms: 10 + -1x = (-5 + x)(x + -5) Reorder the terms: 10 + -1x = (-5 + x)(-5 + x) Multiply (-5 + x) * (-5 + x) 10 + -1x = (-5(-5 + x) + x(-5 + x)) 10 + -1x = ((-5 * -5 + x * -5) + x(-5 + x)) 10 + -1x = ((25 + -5x) + x(-5 + x)) 10 + -1x = (25 + -5x + (-5 * x + x * x)) 10 + -1x = (25 + -5x + (-5x + x2)) Combine like terms: -5x + -5x = -10x 10 + -1x = (25 + -10x + x2) Solving 10 + -1x = 25 + -10x + x2 Solving for variable 'x'. Reorder the terms: 10 + -25 + -1x + 10x + -1x2 = 25 + -10x + x2 + -25 + 10x + -1x2 Combine like terms: 10 + -25 = -15 -15 + -1x + 10x + -1x2 = 25 + -10x + x2 + -25 + 10x + -1x2 Combine like terms: -1x + 10x = 9x -15 + 9x + -1x2 = 25 + -10x + x2 + -25 + 10x + -1x2 Reorder the terms: -15 + 9x + -1x2 = 25 + -25 + -10x + 10x + x2 + -1x2 Combine like terms: 25 + -25 = 0 -15 + 9x + -1x2 = 0 + -10x + 10x + x2 + -1x2 -15 + 9x + -1x2 = -10x + 10x + x2 + -1x2 Combine like terms: -10x + 10x = 0 -15 + 9x + -1x2 = 0 + x2 + -1x2 -15 + 9x + -1x2 = x2 + -1x2 Combine like terms: x2 + -1x2 = 0 -15 + 9x + -1x2 = 0 Begin completing the square. Divide all terms by -1 the coefficient of the squared term: Divide each side by '-1'. 15 + -9x + x2 = 0 Move the constant term to the right: Add '-15' to each side of the equation. 15 + -9x + -15 + x2 = 0 + -15 Reorder the terms: 15 + -15 + -9x + x2 = 0 + -15 Combine like terms: 15 + -15 = 0 0 + -9x + x2 = 0 + -15 -9x + x2 = 0 + -15 Combine like terms: 0 + -15 = -15 -9x + x2 = -15 The x term is -9x. Take half its coefficient (-4.5). Square it (20.25) and add it to both sides. Add '20.25' to each side of the equation. -9x + 20.25 + x2 = -15 + 20.25 Reorder the terms: 20.25 + -9x + x2 = -15 + 20.25 Combine like terms: -15 + 20.25 = 5.25 20.25 + -9x + x2 = 5.25 Factor a perfect square on the left side: (x + -4.5)(x + -4.5) = 5.25 Calculate the square root of the right side: 2.291287847 Break this problem into two subproblems by setting (x + -4.5) equal to 2.291287847 and -2.291287847.Subproblem 1
x + -4.5 = 2.291287847 Simplifying x + -4.5 = 2.291287847 Reorder the terms: -4.5 + x = 2.291287847 Solving -4.5 + x = 2.291287847 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '4.5' to each side of the equation. -4.5 + 4.5 + x = 2.291287847 + 4.5 Combine like terms: -4.5 + 4.5 = 0.0 0.0 + x = 2.291287847 + 4.5 x = 2.291287847 + 4.5 Combine like terms: 2.291287847 + 4.5 = 6.791287847 x = 6.791287847 Simplifying x = 6.791287847Subproblem 2
