Simplifying -3x2 + 18x = -30 Reorder the terms: 18x + -3x2 = -30 Solving 18x + -3x2 = -30 Solving for variable 'x'. Reorder the terms: 30 + 18x + -3x2 = -30 + 30 Combine like terms: -30 + 30 = 0 30 + 18x + -3x2 = 0 Factor out the Greatest Common Factor (GCF), '3'. 3(10 + 6x + -1x2) = 0 Ignore the factor 3.Subproblem 1
Set the factor '(10 + 6x + -1x2)' equal to zero and attempt to solve: Simplifying 10 + 6x + -1x2 = 0 Solving 10 + 6x + -1x2 = 0 Begin completing the square. Divide all terms by -1 the coefficient of the squared term: Divide each side by '-1'. -10 + -6x + x2 = 0 Move the constant term to the right: Add '10' to each side of the equation. -10 + -6x + 10 + x2 = 0 + 10 Reorder the terms: -10 + 10 + -6x + x2 = 0 + 10 Combine like terms: -10 + 10 = 0 0 + -6x + x2 = 0 + 10 -6x + x2 = 0 + 10 Combine like terms: 0 + 10 = 10 -6x + x2 = 10 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 = 10 + 9 Reorder the terms: 9 + -6x + x2 = 10 + 9 Combine like terms: 10 + 9 = 19 9 + -6x + x2 = 19 Factor a perfect square on the left side: (x + -3)(x + -3) = 19 Calculate the square root of the right side: 4.358898944 Break this problem into two subproblems by setting (x + -3) equal to 4.358898944 and -4.358898944.Subproblem 1
x + -3 = 4.358898944 Simplifying x + -3 = 4.358898944 Reorder the terms: -3 + x = 4.358898944 Solving -3 + x = 4.358898944 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 = 4.358898944 + 3 Combine like terms: -3 + 3 = 0 0 + x = 4.358898944 + 3 x = 4.358898944 + 3 Combine like terms: 4.358898944 + 3 = 7.358898944 x = 7.358898944 Simplifying x = 7.358898944Subproblem 2
x + -3 = -4.358898944 Simplifying x + -3 = -4.358898944 Reorder the terms: -3 + x = -4.358898944 Solving -3 + x = -4.358898944 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 = -4.358898944 + 3 Combine like terms: -3 + 3 = 0 0 + x = -4.358898944 + 3 x = -4.358898944 + 3 Combine like terms: -4.358898944 + 3 = -1.358898944 x = -1.358898944 Simplifying x = -1.358898944Solution
