Simplifying -3x2 + 30x + -39 = 0 Reorder the terms: -39 + 30x + -3x2 = 0 Solving -39 + 30x + -3x2 = 0 Solving for variable 'x'. Factor out the Greatest Common Factor (GCF), '3'. 3(-13 + 10x + -1x2) = 0 Ignore the factor 3.Subproblem 1
Set the factor '(-13 + 10x + -1x2)' equal to zero and attempt to solve: Simplifying -13 + 10x + -1x2 = 0 Solving -13 + 10x + -1x2 = 0 Begin completing the square. Divide all terms by -1 the coefficient of the squared term: Divide each side by '-1'. 13 + -10x + x2 = 0 Move the constant term to the right: Add '-13' to each side of the equation. 13 + -10x + -13 + x2 = 0 + -13 Reorder the terms: 13 + -13 + -10x + x2 = 0 + -13 Combine like terms: 13 + -13 = 0 0 + -10x + x2 = 0 + -13 -10x + x2 = 0 + -13 Combine like terms: 0 + -13 = -13 -10x + x2 = -13 The x term is -10x. Take half its coefficient (-5). Square it (25) and add it to both sides. Add '25' to each side of the equation. -10x + 25 + x2 = -13 + 25 Reorder the terms: 25 + -10x + x2 = -13 + 25 Combine like terms: -13 + 25 = 12 25 + -10x + x2 = 12 Factor a perfect square on the left side: (x + -5)(x + -5) = 12 Calculate the square root of the right side: 3.464101615 Break this problem into two subproblems by setting (x + -5) equal to 3.464101615 and -3.464101615.Subproblem 1
x + -5 = 3.464101615 Simplifying x + -5 = 3.464101615 Reorder the terms: -5 + x = 3.464101615 Solving -5 + x = 3.464101615 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '5' to each side of the equation. -5 + 5 + x = 3.464101615 + 5 Combine like terms: -5 + 5 = 0 0 + x = 3.464101615 + 5 x = 3.464101615 + 5 Combine like terms: 3.464101615 + 5 = 8.464101615 x = 8.464101615 Simplifying x = 8.464101615Subproblem 2
x + -5 = -3.464101615 Simplifying x + -5 = -3.464101615 Reorder the terms: -5 + x = -3.464101615 Solving -5 + x = -3.464101615 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '5' to each side of the equation. -5 + 5 + x = -3.464101615 + 5 Combine like terms: -5 + 5 = 0 0 + x = -3.464101615 + 5 x = -3.464101615 + 5 Combine like terms: -3.464101615 + 5 = 1.535898385 x = 1.535898385 Simplifying x = 1.535898385Solution
