Simplifying 3h2 + -20h + 39 = 0 Reorder the terms: 39 + -20h + 3h2 = 0 Solving 39 + -20h + 3h2 = 0 Solving for variable 'h'. Begin completing the square. Divide all terms by 3 the coefficient of the squared term: Divide each side by '3'. 13 + -6.666666667h + h2 = 0 Move the constant term to the right: Add '-13' to each side of the equation. 13 + -6.666666667h + -13 + h2 = 0 + -13 Reorder the terms: 13 + -13 + -6.666666667h + h2 = 0 + -13 Combine like terms: 13 + -13 = 0 0 + -6.666666667h + h2 = 0 + -13 -6.666666667h + h2 = 0 + -13 Combine like terms: 0 + -13 = -13 -6.666666667h + h2 = -13 The h term is -6.666666667h. Take half its coefficient (-3.333333334). Square it (11.11111112) and add it to both sides. Add '11.11111112' to each side of the equation. -6.666666667h + 11.11111112 + h2 = -13 + 11.11111112 Reorder the terms: 11.11111112 + -6.666666667h + h2 = -13 + 11.11111112 Combine like terms: -13 + 11.11111112 = -1.88888888 11.11111112 + -6.666666667h + h2 = -1.88888888 Factor a perfect square on the left side: (h + -3.333333334)(h + -3.333333334) = -1.88888888 Can't calculate square root of the right side. The solution to this equation could not be determined.
