Simplifying 4x2 + 12x + -63 = 0 Reorder the terms: -63 + 12x + 4x2 = 0 Solving -63 + 12x + 4x2 = 0 Solving for variable 'x'. Begin completing the square. Divide all terms by 4 the coefficient of the squared term: Divide each side by '4'. -15.75 + 3x + x2 = 0 Move the constant term to the right: Add '15.75' to each side of the equation. -15.75 + 3x + 15.75 + x2 = 0 + 15.75 Reorder the terms: -15.75 + 15.75 + 3x + x2 = 0 + 15.75 Combine like terms: -15.75 + 15.75 = 0.00 0.00 + 3x + x2 = 0 + 15.75 3x + x2 = 0 + 15.75 Combine like terms: 0 + 15.75 = 15.75 3x + x2 = 15.75 The x term is 3x. Take half its coefficient (1.5). Square it (2.25) and add it to both sides. Add '2.25' to each side of the equation. 3x + 2.25 + x2 = 15.75 + 2.25 Reorder the terms: 2.25 + 3x + x2 = 15.75 + 2.25 Combine like terms: 15.75 + 2.25 = 18 2.25 + 3x + x2 = 18 Factor a perfect square on the left side: (x + 1.5)(x + 1.5) = 18 Calculate the square root of the right side: 4.242640687 Break this problem into two subproblems by setting (x + 1.5) equal to 4.242640687 and -4.242640687.Subproblem 1
x + 1.5 = 4.242640687 Simplifying x + 1.5 = 4.242640687 Reorder the terms: 1.5 + x = 4.242640687 Solving 1.5 + x = 4.242640687 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-1.5' to each side of the equation. 1.5 + -1.5 + x = 4.242640687 + -1.5 Combine like terms: 1.5 + -1.5 = 0.0 0.0 + x = 4.242640687 + -1.5 x = 4.242640687 + -1.5 Combine like terms: 4.242640687 + -1.5 = 2.742640687 x = 2.742640687 Simplifying x = 2.742640687Subproblem 2
x + 1.5 = -4.242640687 Simplifying x + 1.5 = -4.242640687 Reorder the terms: 1.5 + x = -4.242640687 Solving 1.5 + x = -4.242640687 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-1.5' to each side of the equation. 1.5 + -1.5 + x = -4.242640687 + -1.5 Combine like terms: 1.5 + -1.5 = 0.0 0.0 + x = -4.242640687 + -1.5 x = -4.242640687 + -1.5 Combine like terms: -4.242640687 + -1.5 = -5.742640687 x = -5.742640687 Simplifying x = -5.742640687Solution
