Simplifying 5x2 + -21x + 12 = 0 Reorder the terms: 12 + -21x + 5x2 = 0 Solving 12 + -21x + 5x2 = 0 Solving for variable 'x'. Begin completing the square. Divide all terms by 5 the coefficient of the squared term: Divide each side by '5'. 2.4 + -4.2x + x2 = 0 Move the constant term to the right: Add '-2.4' to each side of the equation. 2.4 + -4.2x + -2.4 + x2 = 0 + -2.4 Reorder the terms: 2.4 + -2.4 + -4.2x + x2 = 0 + -2.4 Combine like terms: 2.4 + -2.4 = 0.0 0.0 + -4.2x + x2 = 0 + -2.4 -4.2x + x2 = 0 + -2.4 Combine like terms: 0 + -2.4 = -2.4 -4.2x + x2 = -2.4 The x term is -4.2x. Take half its coefficient (-2.1). Square it (4.41) and add it to both sides. Add '4.41' to each side of the equation. -4.2x + 4.41 + x2 = -2.4 + 4.41 Reorder the terms: 4.41 + -4.2x + x2 = -2.4 + 4.41 Combine like terms: -2.4 + 4.41 = 2.01 4.41 + -4.2x + x2 = 2.01 Factor a perfect square on the left side: (x + -2.1)(x + -2.1) = 2.01 Calculate the square root of the right side: 1.417744688 Break this problem into two subproblems by setting (x + -2.1) equal to 1.417744688 and -1.417744688.Subproblem 1
x + -2.1 = 1.417744688 Simplifying x + -2.1 = 1.417744688 Reorder the terms: -2.1 + x = 1.417744688 Solving -2.1 + x = 1.417744688 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '2.1' to each side of the equation. -2.1 + 2.1 + x = 1.417744688 + 2.1 Combine like terms: -2.1 + 2.1 = 0.0 0.0 + x = 1.417744688 + 2.1 x = 1.417744688 + 2.1 Combine like terms: 1.417744688 + 2.1 = 3.517744688 x = 3.517744688 Simplifying x = 3.517744688Subproblem 2
x + -2.1 = -1.417744688 Simplifying x + -2.1 = -1.417744688 Reorder the terms: -2.1 + x = -1.417744688 Solving -2.1 + x = -1.417744688 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '2.1' to each side of the equation. -2.1 + 2.1 + x = -1.417744688 + 2.1 Combine like terms: -2.1 + 2.1 = 0.0 0.0 + x = -1.417744688 + 2.1 x = -1.417744688 + 2.1 Combine like terms: -1.417744688 + 2.1 = 0.682255312 x = 0.682255312 Simplifying x = 0.682255312Solution
