Simplifying 12x(x + 3) = 15x + -4 Reorder the terms: 12x(3 + x) = 15x + -4 (3 * 12x + x * 12x) = 15x + -4 (36x + 12x2) = 15x + -4 Reorder the terms: 36x + 12x2 = -4 + 15x Solving 36x + 12x2 = -4 + 15x Solving for variable 'x'. Reorder the terms: 4 + 36x + -15x + 12x2 = -4 + 15x + 4 + -15x Combine like terms: 36x + -15x = 21x 4 + 21x + 12x2 = -4 + 15x + 4 + -15x Reorder the terms: 4 + 21x + 12x2 = -4 + 4 + 15x + -15x Combine like terms: -4 + 4 = 0 4 + 21x + 12x2 = 0 + 15x + -15x 4 + 21x + 12x2 = 15x + -15x Combine like terms: 15x + -15x = 0 4 + 21x + 12x2 = 0 Begin completing the square. Divide all terms by 12 the coefficient of the squared term: Divide each side by '12'. 0.3333333333 + 1.75x + x2 = 0 Move the constant term to the right: Add '-0.3333333333' to each side of the equation. 0.3333333333 + 1.75x + -0.3333333333 + x2 = 0 + -0.3333333333 Reorder the terms: 0.3333333333 + -0.3333333333 + 1.75x + x2 = 0 + -0.3333333333 Combine like terms: 0.3333333333 + -0.3333333333 = 0.0000000000 0.0000000000 + 1.75x + x2 = 0 + -0.3333333333 1.75x + x2 = 0 + -0.3333333333 Combine like terms: 0 + -0.3333333333 = -0.3333333333 1.75x + x2 = -0.3333333333 The x term is 1.75x. Take half its coefficient (0.875). Square it (0.765625) and add it to both sides. Add '0.765625' to each side of the equation. 1.75x + 0.765625 + x2 = -0.3333333333 + 0.765625 Reorder the terms: 0.765625 + 1.75x + x2 = -0.3333333333 + 0.765625 Combine like terms: -0.3333333333 + 0.765625 = 0.4322916667 0.765625 + 1.75x + x2 = 0.4322916667 Factor a perfect square on the left side: (x + 0.875)(x + 0.875) = 0.4322916667 Calculate the square root of the right side: 0.65748891 Break this problem into two subproblems by setting (x + 0.875) equal to 0.65748891 and -0.65748891.Subproblem 1
x + 0.875 = 0.65748891 Simplifying x + 0.875 = 0.65748891 Reorder the terms: 0.875 + x = 0.65748891 Solving 0.875 + x = 0.65748891 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-0.875' to each side of the equation. 0.875 + -0.875 + x = 0.65748891 + -0.875 Combine like terms: 0.875 + -0.875 = 0.000 0.000 + x = 0.65748891 + -0.875 x = 0.65748891 + -0.875 Combine like terms: 0.65748891 + -0.875 = -0.21751109 x = -0.21751109 Simplifying x = -0.21751109Subproblem 2
x + 0.875 = -0.65748891 Simplifying x + 0.875 = -0.65748891 Reorder the terms: 0.875 + x = -0.65748891 Solving 0.875 + x = -0.65748891 Solving for variable 'x'.
