Simplifying -3X(-6 + 3X) = -6 (-6 * -3X + 3X * -3X) = -6 (18X + -9X2) = -6 Solving 18X + -9X2 = -6 Solving for variable 'X'. Reorder the terms: 6 + 18X + -9X2 = -6 + 6 Combine like terms: -6 + 6 = 0 6 + 18X + -9X2 = 0 Factor out the Greatest Common Factor (GCF), '3'. 3(2 + 6X + -3X2) = 0 Ignore the factor 3.Subproblem 1
Set the factor '(2 + 6X + -3X2)' equal to zero and attempt to solve: Simplifying 2 + 6X + -3X2 = 0 Solving 2 + 6X + -3X2 = 0 Begin completing the square. Divide all terms by -3 the coefficient of the squared term: Divide each side by '-3'. -0.6666666667 + -2X + X2 = 0 Move the constant term to the right: Add '0.6666666667' to each side of the equation. -0.6666666667 + -2X + 0.6666666667 + X2 = 0 + 0.6666666667 Reorder the terms: -0.6666666667 + 0.6666666667 + -2X + X2 = 0 + 0.6666666667 Combine like terms: -0.6666666667 + 0.6666666667 = 0.0000000000 0.0000000000 + -2X + X2 = 0 + 0.6666666667 -2X + X2 = 0 + 0.6666666667 Combine like terms: 0 + 0.6666666667 = 0.6666666667 -2X + X2 = 0.6666666667 The X term is -2X. Take half its coefficient (-1). Square it (1) and add it to both sides. Add '1' to each side of the equation. -2X + 1 + X2 = 0.6666666667 + 1 Reorder the terms: 1 + -2X + X2 = 0.6666666667 + 1 Combine like terms: 0.6666666667 + 1 = 1.6666666667 1 + -2X + X2 = 1.6666666667 Factor a perfect square on the left side: (X + -1)(X + -1) = 1.6666666667 Calculate the square root of the right side: 1.290994449 Break this problem into two subproblems by setting (X + -1) equal to 1.290994449 and -1.290994449.Subproblem 1
X + -1 = 1.290994449 Simplifying X + -1 = 1.290994449 Reorder the terms: -1 + X = 1.290994449 Solving -1 + X = 1.290994449 Solving for variable 'X'. Move all terms containing X to the left, all other terms to the right. Add '1' to each side of the equation. -1 + 1 + X = 1.290994449 + 1 Combine like terms: -1 + 1 = 0 0 + X = 1.290994449 + 1 X = 1.290994449 + 1 Combine like terms: 1.290994449 + 1 = 2.290994449 X = 2.290994449 Simplifying X = 2.290994449Subproblem 2
X + -1 = -1.290994449 Simplifying X + -1 = -1.290994449 Reorder the terms: -1 + X = -1.290994449 Solving -1 + X = -1.290994449 Solving for variable 'X'. Move all terms containing X to the left, all other terms to the right. Add '1' to each side of the equation. -1 + 1 + X = -1.290994449 + 1 Combine like terms: -1 + 1 = 0 0 + X = -1.290994449 + 1 X = -1.290994449 + 1 Combine like terms: -1.290994449 + 1 = -0.290994449 X = -0.290994449 Simplifying X = -0.290994449Solution
