Simplifying r2 + -3r + 10 = 0 Reorder the terms: 10 + -3r + r2 = 0 Solving 10 + -3r + r2 = 0 Solving for variable 'r'. Begin completing the square. Move the constant term to the right: Add '-10' to each side of the equation. 10 + -3r + -10 + r2 = 0 + -10 Reorder the terms: 10 + -10 + -3r + r2 = 0 + -10 Combine like terms: 10 + -10 = 0 0 + -3r + r2 = 0 + -10 -3r + r2 = 0 + -10 Combine like terms: 0 + -10 = -10 -3r + r2 = -10 The r term is -3r. Take half its coefficient (-1.5). Square it (2.25) and add it to both sides. Add '2.25' to each side of the equation. -3r + 2.25 + r2 = -10 + 2.25 Reorder the terms: 2.25 + -3r + r2 = -10 + 2.25 Combine like terms: -10 + 2.25 = -7.75 2.25 + -3r + r2 = -7.75 Factor a perfect square on the left side: (r + -1.5)(r + -1.5) = -7.75 Can't calculate square root of the right side. The solution to this equation could not be determined.
