Simplifying 784 + 2r2 = 64 + 8r + 8r Combine like terms: 8r + 8r = 16r 784 + 2r2 = 64 + 16r Solving 784 + 2r2 = 64 + 16r Solving for variable 'r'. Reorder the terms: 784 + -64 + -16r + 2r2 = 64 + 16r + -64 + -16r Combine like terms: 784 + -64 = 720 720 + -16r + 2r2 = 64 + 16r + -64 + -16r Reorder the terms: 720 + -16r + 2r2 = 64 + -64 + 16r + -16r Combine like terms: 64 + -64 = 0 720 + -16r + 2r2 = 0 + 16r + -16r 720 + -16r + 2r2 = 16r + -16r Combine like terms: 16r + -16r = 0 720 + -16r + 2r2 = 0 Factor out the Greatest Common Factor (GCF), '2'. 2(360 + -8r + r2) = 0 Ignore the factor 2.Subproblem 1
Set the factor '(360 + -8r + r2)' equal to zero and attempt to solve: Simplifying 360 + -8r + r2 = 0 Solving 360 + -8r + r2 = 0 Begin completing the square. Move the constant term to the right: Add '-360' to each side of the equation. 360 + -8r + -360 + r2 = 0 + -360 Reorder the terms: 360 + -360 + -8r + r2 = 0 + -360 Combine like terms: 360 + -360 = 0 0 + -8r + r2 = 0 + -360 -8r + r2 = 0 + -360 Combine like terms: 0 + -360 = -360 -8r + r2 = -360 The r term is -8r. Take half its coefficient (-4). Square it (16) and add it to both sides. Add '16' to each side of the equation. -8r + 16 + r2 = -360 + 16 Reorder the terms: 16 + -8r + r2 = -360 + 16 Combine like terms: -360 + 16 = -344 16 + -8r + r2 = -344 Factor a perfect square on the left side: (r + -4)(r + -4) = -344 Can't calculate square root of the right side.
