Simplifying 7r2 + -5 = 2r + 9r2 Reorder the terms: -5 + 7r2 = 2r + 9r2 Solving -5 + 7r2 = 2r + 9r2 Solving for variable 'r'. Reorder the terms: -5 + -2r + 7r2 + -9r2 = 2r + 9r2 + -2r + -9r2 Combine like terms: 7r2 + -9r2 = -2r2 -5 + -2r + -2r2 = 2r + 9r2 + -2r + -9r2 Reorder the terms: -5 + -2r + -2r2 = 2r + -2r + 9r2 + -9r2 Combine like terms: 2r + -2r = 0 -5 + -2r + -2r2 = 0 + 9r2 + -9r2 -5 + -2r + -2r2 = 9r2 + -9r2 Combine like terms: 9r2 + -9r2 = 0 -5 + -2r + -2r2 = 0 Factor out the Greatest Common Factor (GCF), '-1'. -1(5 + 2r + 2r2) = 0 Ignore the factor -1.Subproblem 1
Set the factor '(5 + 2r + 2r2)' equal to zero and attempt to solve: Simplifying 5 + 2r + 2r2 = 0 Solving 5 + 2r + 2r2 = 0 Begin completing the square. Divide all terms by 2 the coefficient of the squared term: Divide each side by '2'. 2.5 + r + r2 = 0 Move the constant term to the right: Add '-2.5' to each side of the equation. 2.5 + r + -2.5 + r2 = 0 + -2.5 Reorder the terms: 2.5 + -2.5 + r + r2 = 0 + -2.5 Combine like terms: 2.5 + -2.5 = 0.0 0.0 + r + r2 = 0 + -2.5 r + r2 = 0 + -2.5 Combine like terms: 0 + -2.5 = -2.5 r + r2 = -2.5 The r term is r. Take half its coefficient (0.5). Square it (0.25) and add it to both sides. Add '0.25' to each side of the equation. + 0.25 + r2 = -2.5 + 0.25 Combine like terms: + 0.25 = 1.25 1.25 + r2 = -2.5 + 0.25 Combine like terms: -2.5 + 0.25 = -2.25 1.25 + r2 = -2.25 Factor a perfect square on the left side: (r + 0.5)(r + 0.5) = -2.25 Can't calculate square root of the right side.
