Simplifying (2x + -5)(6 + x) = 2x + -7x + 12 Reorder the terms: (-5 + 2x)(6 + x) = 2x + -7x + 12 Multiply (-5 + 2x) * (6 + x) (-5(6 + x) + 2x * (6 + x)) = 2x + -7x + 12 ((6 * -5 + x * -5) + 2x * (6 + x)) = 2x + -7x + 12 ((-30 + -5x) + 2x * (6 + x)) = 2x + -7x + 12 (-30 + -5x + (6 * 2x + x * 2x)) = 2x + -7x + 12 (-30 + -5x + (12x + 2x2)) = 2x + -7x + 12 Combine like terms: -5x + 12x = 7x (-30 + 7x + 2x2) = 2x + -7x + 12 Reorder the terms: -30 + 7x + 2x2 = 12 + 2x + -7x Combine like terms: 2x + -7x = -5x -30 + 7x + 2x2 = 12 + -5x Solving -30 + 7x + 2x2 = 12 + -5x Solving for variable 'x'. Reorder the terms: -30 + -12 + 7x + 5x + 2x2 = 12 + -5x + -12 + 5x Combine like terms: -30 + -12 = -42 -42 + 7x + 5x + 2x2 = 12 + -5x + -12 + 5x Combine like terms: 7x + 5x = 12x -42 + 12x + 2x2 = 12 + -5x + -12 + 5x Reorder the terms: -42 + 12x + 2x2 = 12 + -12 + -5x + 5x Combine like terms: 12 + -12 = 0 -42 + 12x + 2x2 = 0 + -5x + 5x -42 + 12x + 2x2 = -5x + 5x Combine like terms: -5x + 5x = 0 -42 + 12x + 2x2 = 0 Factor out the Greatest Common Factor (GCF), '2'. 2(-21 + 6x + x2) = 0 Ignore the factor 2.Subproblem 1
Set the factor '(-21 + 6x + x2)' equal to zero and attempt to solve: Simplifying -21 + 6x + x2 = 0 Solving -21 + 6x + x2 = 0 Begin completing the square. Move the constant term to the right: Add '21' to each side of the equation. -21 + 6x + 21 + x2 = 0 + 21 Reorder the terms: -21 + 21 + 6x + x2 = 0 + 21 Combine like terms: -21 + 21 = 0 0 + 6x + x2 = 0 + 21 6x + x2 = 0 + 21 Combine like terms: 0 + 21 = 21 6x + x2 = 21 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 = 21 + 9 Reorder the terms: 9 + 6x + x2 = 21 + 9 Combine like terms: 21 + 9 = 30 9 + 6x + x2 = 30 Factor a perfect square on the left side: (x + 3)(x + 3) = 30 Calculate the square root of the right side: 5.477225575 Break this problem into two subproblems by setting (x + 3) equal to 5.477225575 and -5.477225575.Subproblem 1
x + 3 = 5.477225575 Simplifying x + 3 = 5.477225575 Reorder the terms: 3 + x = 5.477225575 Solving 3 + x = 5.477225575 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 = 5.477225575 + -3 Combine like terms: 3 + -3 = 0 0 + x = 5.477225575 + -3 x = 5.477225575 + -3 Combine like terms: 5.477225575 + -3 = 2.477225575 x = 2.477225575 Simplifying x = 2.477225575Subproblem 2
x + 3 = -5.477225575 Simplifying x + 3 = -5.477225575 Reorder the terms: 3 + x = -5.477225575 Solving 3 + x = -5.477225575 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 = -5.477225575 + -3 Combine like terms: 3 + -3 = 0 0 + x = -5.477225575 + -3 x = -5.477225575 + -3 Combine like terms: -5.477225575 + -3 = -8.477225575 x = -8.477225575 Simplifying x = -8.477225575Solution
