Simplifying 2(x + -3)(x + -2) = x + 2 + -1(x + -4) Reorder the terms: 2(-3 + x)(x + -2) = x + 2 + -1(x + -4) Reorder the terms: 2(-3 + x)(-2 + x) = x + 2 + -1(x + -4) Multiply (-3 + x) * (-2 + x) 2(-3(-2 + x) + x(-2 + x)) = x + 2 + -1(x + -4) 2((-2 * -3 + x * -3) + x(-2 + x)) = x + 2 + -1(x + -4) 2((6 + -3x) + x(-2 + x)) = x + 2 + -1(x + -4) 2(6 + -3x + (-2 * x + x * x)) = x + 2 + -1(x + -4) 2(6 + -3x + (-2x + x2)) = x + 2 + -1(x + -4) Combine like terms: -3x + -2x = -5x 2(6 + -5x + x2) = x + 2 + -1(x + -4) (6 * 2 + -5x * 2 + x2 * 2) = x + 2 + -1(x + -4) (12 + -10x + 2x2) = x + 2 + -1(x + -4) Reorder the terms: 12 + -10x + 2x2 = x + 2 + -1(-4 + x) 12 + -10x + 2x2 = x + 2 + (-4 * -1 + x * -1) 12 + -10x + 2x2 = x + 2 + (4 + -1x) Reorder the terms: 12 + -10x + 2x2 = 2 + 4 + x + -1x Combine like terms: 2 + 4 = 6 12 + -10x + 2x2 = 6 + x + -1x Combine like terms: x + -1x = 0 12 + -10x + 2x2 = 6 + 0 12 + -10x + 2x2 = 6 Solving 12 + -10x + 2x2 = 6 Solving for variable 'x'. Reorder the terms: 12 + -6 + -10x + 2x2 = 6 + -6 Combine like terms: 12 + -6 = 6 6 + -10x + 2x2 = 6 + -6 Combine like terms: 6 + -6 = 0 6 + -10x + 2x2 = 0 Factor out the Greatest Common Factor (GCF), '2'. 2(3 + -5x + x2) = 0 Ignore the factor 2.Subproblem 1
Set the factor '(3 + -5x + x2)' equal to zero and attempt to solve: Simplifying 3 + -5x + x2 = 0 Solving 3 + -5x + x2 = 0 Begin completing the square. Move the constant term to the right: Add '-3' to each side of the equation. 3 + -5x + -3 + x2 = 0 + -3 Reorder the terms: 3 + -3 + -5x + x2 = 0 + -3 Combine like terms: 3 + -3 = 0 0 + -5x + x2 = 0 + -3 -5x + x2 = 0 + -3 Combine like terms: 0 + -3 = -3 -5x + x2 = -3 The x term is -5x. Take half its coefficient (-2.5). Square it (6.25) and add it to both sides. Add '6.25' to each side of the equation. -5x + 6.25 + x2 = -3 + 6.25 Reorder the terms: 6.25 + -5x + x2 = -3 + 6.25 Combine like terms: -3 + 6.25 = 3.25 6.25 + -5x + x2 = 3.25 Factor a perfect square on the left side: (x + -2.5)(x + -2.5) = 3.25 Calculate the square root of the right side: 1.802775638 Break this problem into two subproblems by setting (x + -2.5) equal to 1.802775638 and -1.802775638.Subproblem 1
x + -2.5 = 1.802775638 Simplifying x + -2.5 = 1.802775638 Reorder the terms: -2.5 + x = 1.802775638 Solving -2.5 + x = 1.802775638 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '2.5' to each side of the equation. -2.5 + 2.5 + x = 1.802775638 + 2.5 Combine like terms: -2.5 + 2.5 = 0.0 0.0 + x = 1.802775638 + 2.5 x = 1.802775638 + 2.5 Combine like terms: 1.802775638 + 2.5 = 4.302775638 x = 4.302775638 Simplifying x = 4.302775638Subproblem 2
x + -2.5 = -1.802775638 Simplifying x + -2.5 = -1.802775638 Reorder the terms: -2.5 + x = -1.802775638 Solving -2.5 + x = -1.802775638 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '2.5' to each side of the equation. -2.5 + 2.5 + x = -1.802775638 + 2.5 Combine like terms: -2.5 + 2.5 = 0.0 0.0 + x = -1.802775638 + 2.5 x = -1.802775638 + 2.5 Combine like terms: -1.802775638 + 2.5 = 0.697224362 x = 0.697224362 Simplifying x = 0.697224362Solution
