Simplifying 10r2 + -20r + 58 = 0 Reorder the terms: 58 + -20r + 10r2 = 0 Solving 58 + -20r + 10r2 = 0 Solving for variable 'r'. Factor out the Greatest Common Factor (GCF), '2'. 2(29 + -10r + 5r2) = 0 Ignore the factor 2.Subproblem 1
Set the factor '(29 + -10r + 5r2)' equal to zero and attempt to solve: Simplifying 29 + -10r + 5r2 = 0 Solving 29 + -10r + 5r2 = 0 Begin completing the square. Divide all terms by 5 the coefficient of the squared term: Divide each side by '5'. 5.8 + -2r + r2 = 0 Move the constant term to the right: Add '-5.8' to each side of the equation. 5.8 + -2r + -5.8 + r2 = 0 + -5.8 Reorder the terms: 5.8 + -5.8 + -2r + r2 = 0 + -5.8 Combine like terms: 5.8 + -5.8 = 0.0 0.0 + -2r + r2 = 0 + -5.8 -2r + r2 = 0 + -5.8 Combine like terms: 0 + -5.8 = -5.8 -2r + r2 = -5.8 The r term is -2r. Take half its coefficient (-1). Square it (1) and add it to both sides. Add '1' to each side of the equation. -2r + 1 + r2 = -5.8 + 1 Reorder the terms: 1 + -2r + r2 = -5.8 + 1 Combine like terms: -5.8 + 1 = -4.8 1 + -2r + r2 = -4.8 Factor a perfect square on the left side: (r + -1)(r + -1) = -4.8 Can't calculate square root of the right side.
