Simplifying 10r + 70 + 49 + -1r2 = 169 Reorder the terms: 70 + 49 + 10r + -1r2 = 169 Combine like terms: 70 + 49 = 119 119 + 10r + -1r2 = 169 Solving 119 + 10r + -1r2 = 169 Solving for variable 'r'. Reorder the terms: 119 + -169 + 10r + -1r2 = 169 + -169 Combine like terms: 119 + -169 = -50 -50 + 10r + -1r2 = 169 + -169 Combine like terms: 169 + -169 = 0 -50 + 10r + -1r2 = 0 Begin completing the square. Divide all terms by -1 the coefficient of the squared term: Divide each side by '-1'. 50 + -10r + r2 = 0 Move the constant term to the right: Add '-50' to each side of the equation. 50 + -10r + -50 + r2 = 0 + -50 Reorder the terms: 50 + -50 + -10r + r2 = 0 + -50 Combine like terms: 50 + -50 = 0 0 + -10r + r2 = 0 + -50 -10r + r2 = 0 + -50 Combine like terms: 0 + -50 = -50 -10r + r2 = -50 The r term is -10r. Take half its coefficient (-5). Square it (25) and add it to both sides. Add '25' to each side of the equation. -10r + 25 + r2 = -50 + 25 Reorder the terms: 25 + -10r + r2 = -50 + 25 Combine like terms: -50 + 25 = -25 25 + -10r + r2 = -25 Factor a perfect square on the left side: (r + -5)(r + -5) = -25 Can't calculate square root of the right side. The solution to this equation could not be determined.
