Simplifying 2x2 + -21x + 12 = 0 Reorder the terms: 12 + -21x + 2x2 = 0 Solving 12 + -21x + 2x2 = 0 Solving for variable 'x'. Begin completing the square. Divide all terms by 2 the coefficient of the squared term: Divide each side by '2'. 6 + -10.5x + x2 = 0 Move the constant term to the right: Add '-6' to each side of the equation. 6 + -10.5x + -6 + x2 = 0 + -6 Reorder the terms: 6 + -6 + -10.5x + x2 = 0 + -6 Combine like terms: 6 + -6 = 0 0 + -10.5x + x2 = 0 + -6 -10.5x + x2 = 0 + -6 Combine like terms: 0 + -6 = -6 -10.5x + x2 = -6 The x term is -10.5x. Take half its coefficient (-5.25). Square it (27.5625) and add it to both sides. Add '27.5625' to each side of the equation. -10.5x + 27.5625 + x2 = -6 + 27.5625 Reorder the terms: 27.5625 + -10.5x + x2 = -6 + 27.5625 Combine like terms: -6 + 27.5625 = 21.5625 27.5625 + -10.5x + x2 = 21.5625 Factor a perfect square on the left side: (x + -5.25)(x + -5.25) = 21.5625 Calculate the square root of the right side: 4.643543905 Break this problem into two subproblems by setting (x + -5.25) equal to 4.643543905 and -4.643543905.Subproblem 1
x + -5.25 = 4.643543905 Simplifying x + -5.25 = 4.643543905 Reorder the terms: -5.25 + x = 4.643543905 Solving -5.25 + x = 4.643543905 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '5.25' to each side of the equation. -5.25 + 5.25 + x = 4.643543905 + 5.25 Combine like terms: -5.25 + 5.25 = 0.00 0.00 + x = 4.643543905 + 5.25 x = 4.643543905 + 5.25 Combine like terms: 4.643543905 + 5.25 = 9.893543905 x = 9.893543905 Simplifying x = 9.893543905Subproblem 2
x + -5.25 = -4.643543905 Simplifying x + -5.25 = -4.643543905 Reorder the terms: -5.25 + x = -4.643543905 Solving -5.25 + x = -4.643543905 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '5.25' to each side of the equation. -5.25 + 5.25 + x = -4.643543905 + 5.25 Combine like terms: -5.25 + 5.25 = 0.00 0.00 + x = -4.643543905 + 5.25 x = -4.643543905 + 5.25 Combine like terms: -4.643543905 + 5.25 = 0.606456095 x = 0.606456095 Simplifying x = 0.606456095Solution
