Simplifying 10u2 + -2u + 2 = 0 Reorder the terms: 2 + -2u + 10u2 = 0 Solving 2 + -2u + 10u2 = 0 Solving for variable 'u'. Factor out the Greatest Common Factor (GCF), '2'. 2(1 + -1u + 5u2) = 0 Ignore the factor 2.Subproblem 1
Set the factor '(1 + -1u + 5u2)' equal to zero and attempt to solve: Simplifying 1 + -1u + 5u2 = 0 Solving 1 + -1u + 5u2 = 0 Begin completing the square. Divide all terms by 5 the coefficient of the squared term: Divide each side by '5'. 0.2 + -0.2u + u2 = 0 Move the constant term to the right: Add '-0.2' to each side of the equation. 0.2 + -0.2u + -0.2 + u2 = 0 + -0.2 Reorder the terms: 0.2 + -0.2 + -0.2u + u2 = 0 + -0.2 Combine like terms: 0.2 + -0.2 = 0.0 0.0 + -0.2u + u2 = 0 + -0.2 -0.2u + u2 = 0 + -0.2 Combine like terms: 0 + -0.2 = -0.2 -0.2u + u2 = -0.2 The u term is -0.2u. Take half its coefficient (-0.1). Square it (0.01) and add it to both sides. Add '0.01' to each side of the equation. -0.2u + 0.01 + u2 = -0.2 + 0.01 Reorder the terms: 0.01 + -0.2u + u2 = -0.2 + 0.01 Combine like terms: -0.2 + 0.01 = -0.19 0.01 + -0.2u + u2 = -0.19 Factor a perfect square on the left side: (u + -0.1)(u + -0.1) = -0.19 Can't calculate square root of the right side.
