Simplifying r4 + 4r3 + 5r2 = 0 Reorder the terms: 5r2 + 4r3 + r4 = 0 Solving 5r2 + 4r3 + r4 = 0 Solving for variable 'r'. Factor out the Greatest Common Factor (GCF), 'r2'. r2(5 + 4r + r2) = 0Subproblem 1
Set the factor 'r2' equal to zero and attempt to solve: Simplifying r2 = 0 Solving r2 = 0 Move all terms containing r to the left, all other terms to the right. Simplifying r2 = 0 Take the square root of each side: r = {0}Subproblem 2
Set the factor '(5 + 4r + r2)' equal to zero and attempt to solve: Simplifying 5 + 4r + r2 = 0 Solving 5 + 4r + r2 = 0 Begin completing the square. Move the constant term to the right: Add '-5' to each side of the equation. 5 + 4r + -5 + r2 = 0 + -5 Reorder the terms: 5 + -5 + 4r + r2 = 0 + -5 Combine like terms: 5 + -5 = 0 0 + 4r + r2 = 0 + -5 4r + r2 = 0 + -5 Combine like terms: 0 + -5 = -5 4r + r2 = -5 The r term is 4r. Take half its coefficient (2). Square it (4) and add it to both sides. Add '4' to each side of the equation. 4r + 4 + r2 = -5 + 4 Reorder the terms: 4 + 4r + r2 = -5 + 4 Combine like terms: -5 + 4 = -1 4 + 4r + r2 = -1 Factor a perfect square on the left side: (r + 2)(r + 2) = -1 Can't calculate square root of the right side. The solution to this equation could not be determined. This subproblem is being ignored because a solution could not be determined.Solution
