Simplifying 3v2 + 5v + -18 = 0 Reorder the terms: -18 + 5v + 3v2 = 0 Solving -18 + 5v + 3v2 = 0 Solving for variable 'v'. Begin completing the square. Divide all terms by 3 the coefficient of the squared term: Divide each side by '3'. -6 + 1.666666667v + v2 = 0 Move the constant term to the right: Add '6' to each side of the equation. -6 + 1.666666667v + 6 + v2 = 0 + 6 Reorder the terms: -6 + 6 + 1.666666667v + v2 = 0 + 6 Combine like terms: -6 + 6 = 0 0 + 1.666666667v + v2 = 0 + 6 1.666666667v + v2 = 0 + 6 Combine like terms: 0 + 6 = 6 1.666666667v + v2 = 6 The v term is 1.666666667v. Take half its coefficient (0.8333333335). Square it (0.6944444447) and add it to both sides. Add '0.6944444447' to each side of the equation. 1.666666667v + 0.6944444447 + v2 = 6 + 0.6944444447 Reorder the terms: 0.6944444447 + 1.666666667v + v2 = 6 + 0.6944444447 Combine like terms: 6 + 0.6944444447 = 6.6944444447 0.6944444447 + 1.666666667v + v2 = 6.6944444447 Factor a perfect square on the left side: (v + 0.8333333335)(v + 0.8333333335) = 6.6944444447 Calculate the square root of the right side: 2.587362449 Break this problem into two subproblems by setting (v + 0.8333333335) equal to 2.587362449 and -2.587362449.Subproblem 1
v + 0.8333333335 = 2.587362449 Simplifying v + 0.8333333335 = 2.587362449 Reorder the terms: 0.8333333335 + v = 2.587362449 Solving 0.8333333335 + v = 2.587362449 Solving for variable 'v'.
