Simplifying (24 + -2x)(20 + -2x) = 340 Multiply (24 + -2x) * (20 + -2x) (24(20 + -2x) + -2x * (20 + -2x)) = 340 ((20 * 24 + -2x * 24) + -2x * (20 + -2x)) = 340 ((480 + -48x) + -2x * (20 + -2x)) = 340 (480 + -48x + (20 * -2x + -2x * -2x)) = 340 (480 + -48x + (-40x + 4x2)) = 340 Combine like terms: -48x + -40x = -88x (480 + -88x + 4x2) = 340 Solving 480 + -88x + 4x2 = 340 Solving for variable 'x'. Reorder the terms: 480 + -340 + -88x + 4x2 = 340 + -340 Combine like terms: 480 + -340 = 140 140 + -88x + 4x2 = 340 + -340 Combine like terms: 340 + -340 = 0 140 + -88x + 4x2 = 0 Factor out the Greatest Common Factor (GCF), '4'. 4(35 + -22x + x2) = 0 Ignore the factor 4.Subproblem 1
Set the factor '(35 + -22x + x2)' equal to zero and attempt to solve: Simplifying 35 + -22x + x2 = 0 Solving 35 + -22x + x2 = 0 Begin completing the square. Move the constant term to the right: Add '-35' to each side of the equation. 35 + -22x + -35 + x2 = 0 + -35 Reorder the terms: 35 + -35 + -22x + x2 = 0 + -35 Combine like terms: 35 + -35 = 0 0 + -22x + x2 = 0 + -35 -22x + x2 = 0 + -35 Combine like terms: 0 + -35 = -35 -22x + x2 = -35 The x term is -22x. Take half its coefficient (-11). Square it (121) and add it to both sides. Add '121' to each side of the equation. -22x + 121 + x2 = -35 + 121 Reorder the terms: 121 + -22x + x2 = -35 + 121 Combine like terms: -35 + 121 = 86 121 + -22x + x2 = 86 Factor a perfect square on the left side: (x + -11)(x + -11) = 86 Calculate the square root of the right side: 9.273618495 Break this problem into two subproblems by setting (x + -11) equal to 9.273618495 and -9.273618495.Subproblem 1
x + -11 = 9.273618495 Simplifying x + -11 = 9.273618495 Reorder the terms: -11 + x = 9.273618495 Solving -11 + x = 9.273618495 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '11' to each side of the equation. -11 + 11 + x = 9.273618495 + 11 Combine like terms: -11 + 11 = 0 0 + x = 9.273618495 + 11 x = 9.273618495 + 11 Combine like terms: 9.273618495 + 11 = 20.273618495 x = 20.273618495 Simplifying x = 20.273618495Subproblem 2
x + -11 = -9.273618495 Simplifying x + -11 = -9.273618495 Reorder the terms: -11 + x = -9.273618495 Solving -11 + x = -9.273618495 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '11' to each side of the equation. -11 + 11 + x = -9.273618495 + 11 Combine like terms: -11 + 11 = 0 0 + x = -9.273618495 + 11 x = -9.273618495 + 11 Combine like terms: -9.273618495 + 11 = 1.726381505 x = 1.726381505 Simplifying x = 1.726381505Solution
