Simplifying 16x2 + 18x + 6 = 0 Reorder the terms: 6 + 18x + 16x2 = 0 Solving 6 + 18x + 16x2 = 0 Solving for variable 'x'. Factor out the Greatest Common Factor (GCF), '2'. 2(3 + 9x + 8x2) = 0 Ignore the factor 2.Subproblem 1
Set the factor '(3 + 9x + 8x2)' equal to zero and attempt to solve: Simplifying 3 + 9x + 8x2 = 0 Solving 3 + 9x + 8x2 = 0 Begin completing the square. Divide all terms by 8 the coefficient of the squared term: Divide each side by '8'. 0.375 + 1.125x + x2 = 0 Move the constant term to the right: Add '-0.375' to each side of the equation. 0.375 + 1.125x + -0.375 + x2 = 0 + -0.375 Reorder the terms: 0.375 + -0.375 + 1.125x + x2 = 0 + -0.375 Combine like terms: 0.375 + -0.375 = 0.000 0.000 + 1.125x + x2 = 0 + -0.375 1.125x + x2 = 0 + -0.375 Combine like terms: 0 + -0.375 = -0.375 1.125x + x2 = -0.375 The x term is 1.125x. Take half its coefficient (0.5625). Square it (0.31640625) and add it to both sides. Add '0.31640625' to each side of the equation. 1.125x + 0.31640625 + x2 = -0.375 + 0.31640625 Reorder the terms: 0.31640625 + 1.125x + x2 = -0.375 + 0.31640625 Combine like terms: -0.375 + 0.31640625 = -0.05859375 0.31640625 + 1.125x + x2 = -0.05859375 Factor a perfect square on the left side: (x + 0.5625)(x + 0.5625) = -0.05859375 Can't calculate square root of the right side. The solution to this equation could not be determined. This subproblem is being ignored because a solution could not be determined. The solution to this equation could not be determined.
