Simplifying 18w2 + -6w + 2 = 0 Reorder the terms: 2 + -6w + 18w2 = 0 Solving 2 + -6w + 18w2 = 0 Solving for variable 'w'. Factor out the Greatest Common Factor (GCF), '2'. 2(1 + -3w + 9w2) = 0 Ignore the factor 2.Subproblem 1
Set the factor '(1 + -3w + 9w2)' equal to zero and attempt to solve: Simplifying 1 + -3w + 9w2 = 0 Solving 1 + -3w + 9w2 = 0 Begin completing the square. Divide all terms by 9 the coefficient of the squared term: Divide each side by '9'. 0.1111111111 + -0.3333333333w + w2 = 0 Move the constant term to the right: Add '-0.1111111111' to each side of the equation. 0.1111111111 + -0.3333333333w + -0.1111111111 + w2 = 0 + -0.1111111111 Reorder the terms: 0.1111111111 + -0.1111111111 + -0.3333333333w + w2 = 0 + -0.1111111111 Combine like terms: 0.1111111111 + -0.1111111111 = 0.0000000000 0.0000000000 + -0.3333333333w + w2 = 0 + -0.1111111111 -0.3333333333w + w2 = 0 + -0.1111111111 Combine like terms: 0 + -0.1111111111 = -0.1111111111 -0.3333333333w + w2 = -0.1111111111 The w term is -0.3333333333w. Take half its coefficient (-0.1666666667). Square it (0.02777777779) and add it to both sides. Add '0.02777777779' to each side of the equation. -0.3333333333w + 0.02777777779 + w2 = -0.1111111111 + 0.02777777779 Reorder the terms: 0.02777777779 + -0.3333333333w + w2 = -0.1111111111 + 0.02777777779 Combine like terms: -0.1111111111 + 0.02777777779 = -0.08333333331 0.02777777779 + -0.3333333333w + w2 = -0.08333333331 Factor a perfect square on the left side: (w + -0.1666666667)(w + -0.1666666667) = -0.08333333331 Can't calculate square root of the right side.
