Simplifying 20X2 + -120X + -109 = 0 Reorder the terms: -109 + -120X + 20X2 = 0 Solving -109 + -120X + 20X2 = 0 Solving for variable 'X'. Begin completing the square. Divide all terms by 20 the coefficient of the squared term: Divide each side by '20'. -5.45 + -6X + X2 = 0 Move the constant term to the right: Add '5.45' to each side of the equation. -5.45 + -6X + 5.45 + X2 = 0 + 5.45 Reorder the terms: -5.45 + 5.45 + -6X + X2 = 0 + 5.45 Combine like terms: -5.45 + 5.45 = 0.00 0.00 + -6X + X2 = 0 + 5.45 -6X + X2 = 0 + 5.45 Combine like terms: 0 + 5.45 = 5.45 -6X + X2 = 5.45 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 = 5.45 + 9 Reorder the terms: 9 + -6X + X2 = 5.45 + 9 Combine like terms: 5.45 + 9 = 14.45 9 + -6X + X2 = 14.45 Factor a perfect square on the left side: (X + -3)(X + -3) = 14.45 Calculate the square root of the right side: 3.801315562 Break this problem into two subproblems by setting (X + -3) equal to 3.801315562 and -3.801315562.Subproblem 1
X + -3 = 3.801315562 Simplifying X + -3 = 3.801315562 Reorder the terms: -3 + X = 3.801315562 Solving -3 + X = 3.801315562 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 = 3.801315562 + 3 Combine like terms: -3 + 3 = 0 0 + X = 3.801315562 + 3 X = 3.801315562 + 3 Combine like terms: 3.801315562 + 3 = 6.801315562 X = 6.801315562 Simplifying X = 6.801315562Subproblem 2
X + -3 = -3.801315562 Simplifying X + -3 = -3.801315562 Reorder the terms: -3 + X = -3.801315562 Solving -3 + X = -3.801315562 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 = -3.801315562 + 3 Combine like terms: -3 + 3 = 0 0 + X = -3.801315562 + 3 X = -3.801315562 + 3 Combine like terms: -3.801315562 + 3 = -0.801315562 X = -0.801315562 Simplifying X = -0.801315562Solution
