Simplifying 5x2 + -30x + 12 = 0 Reorder the terms: 12 + -30x + 5x2 = 0 Solving 12 + -30x + 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 + -6x + x2 = 0 Move the constant term to the right: Add '-2.4' to each side of the equation. 2.4 + -6x + -2.4 + x2 = 0 + -2.4 Reorder the terms: 2.4 + -2.4 + -6x + x2 = 0 + -2.4 Combine like terms: 2.4 + -2.4 = 0.0 0.0 + -6x + x2 = 0 + -2.4 -6x + x2 = 0 + -2.4 Combine like terms: 0 + -2.4 = -2.4 -6x + x2 = -2.4 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 = -2.4 + 9 Reorder the terms: 9 + -6x + x2 = -2.4 + 9 Combine like terms: -2.4 + 9 = 6.6 9 + -6x + x2 = 6.6 Factor a perfect square on the left side: (x + -3)(x + -3) = 6.6 Calculate the square root of the right side: 2.569046516 Break this problem into two subproblems by setting (x + -3) equal to 2.569046516 and -2.569046516.Subproblem 1
x + -3 = 2.569046516 Simplifying x + -3 = 2.569046516 Reorder the terms: -3 + x = 2.569046516 Solving -3 + x = 2.569046516 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 = 2.569046516 + 3 Combine like terms: -3 + 3 = 0 0 + x = 2.569046516 + 3 x = 2.569046516 + 3 Combine like terms: 2.569046516 + 3 = 5.569046516 x = 5.569046516 Simplifying x = 5.569046516Subproblem 2
x + -3 = -2.569046516 Simplifying x + -3 = -2.569046516 Reorder the terms: -3 + x = -2.569046516 Solving -3 + x = -2.569046516 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 = -2.569046516 + 3 Combine like terms: -3 + 3 = 0 0 + x = -2.569046516 + 3 x = -2.569046516 + 3 Combine like terms: -2.569046516 + 3 = 0.430953484 x = 0.430953484 Simplifying x = 0.430953484Solution
