Simplifying 10 + -18x + 18x2 = 0 Solving 10 + -18x + 18x2 = 0 Solving for variable 'x'. Factor out the Greatest Common Factor (GCF), '2'. 2(5 + -9x + 9x2) = 0 Ignore the factor 2.Subproblem 1
Set the factor '(5 + -9x + 9x2)' equal to zero and attempt to solve: Simplifying 5 + -9x + 9x2 = 0 Solving 5 + -9x + 9x2 = 0 Begin completing the square. Divide all terms by 9 the coefficient of the squared term: Divide each side by '9'. 0.5555555556 + -1x + x2 = 0 Move the constant term to the right: Add '-0.5555555556' to each side of the equation. 0.5555555556 + -1x + -0.5555555556 + x2 = 0 + -0.5555555556 Reorder the terms: 0.5555555556 + -0.5555555556 + -1x + x2 = 0 + -0.5555555556 Combine like terms: 0.5555555556 + -0.5555555556 = 0.0000000000 0.0000000000 + -1x + x2 = 0 + -0.5555555556 -1x + x2 = 0 + -0.5555555556 Combine like terms: 0 + -0.5555555556 = -0.5555555556 -1x + x2 = -0.5555555556 The x term is -1x. Take half its coefficient (-0.5). Square it (0.25) and add it to both sides. Add '0.25' to each side of the equation. -1x + 0.25 + x2 = -0.5555555556 + 0.25 Reorder the terms: 0.25 + -1x + x2 = -0.5555555556 + 0.25 Combine like terms: -0.5555555556 + 0.25 = -0.3055555556 0.25 + -1x + x2 = -0.3055555556 Factor a perfect square on the left side: (x + -0.5)(x + -0.5) = -0.3055555556 Can't calculate square root of the right side.
