Simplifying 12r2 + -8r + 15 = 0 Reorder the terms: 15 + -8r + 12r2 = 0 Solving 15 + -8r + 12r2 = 0 Solving for variable 'r'. Begin completing the square. Divide all terms by 12 the coefficient of the squared term: Divide each side by '12'. 1.25 + -0.6666666667r + r2 = 0 Move the constant term to the right: Add '-1.25' to each side of the equation. 1.25 + -0.6666666667r + -1.25 + r2 = 0 + -1.25 Reorder the terms: 1.25 + -1.25 + -0.6666666667r + r2 = 0 + -1.25 Combine like terms: 1.25 + -1.25 = 0.00 0.00 + -0.6666666667r + r2 = 0 + -1.25 -0.6666666667r + r2 = 0 + -1.25 Combine like terms: 0 + -1.25 = -1.25 -0.6666666667r + r2 = -1.25 The r term is -0.6666666667r. Take half its coefficient (-0.3333333334). Square it (0.1111111112) and add it to both sides. Add '0.1111111112' to each side of the equation. -0.6666666667r + 0.1111111112 + r2 = -1.25 + 0.1111111112 Reorder the terms: 0.1111111112 + -0.6666666667r + r2 = -1.25 + 0.1111111112 Combine like terms: -1.25 + 0.1111111112 = -1.1388888888 0.1111111112 + -0.6666666667r + r2 = -1.1388888888 Factor a perfect square on the left side: (r + -0.3333333334)(r + -0.3333333334) = -1.1388888888 Can't calculate square root of the right side. The solution to this equation could not be determined.
