Simplifying 4x2 + 24x + 84 = 0 Reorder the terms: 84 + 24x + 4x2 = 0 Solving 84 + 24x + 4x2 = 0 Solving for variable 'x'. Factor out the Greatest Common Factor (GCF), '4'. 4(21 + 6x + x2) = 0 Ignore the factor 4.Subproblem 1
Set the factor '(21 + 6x + x2)' equal to zero and attempt to solve: Simplifying 21 + 6x + x2 = 0 Solving 21 + 6x + x2 = 0 Begin completing the square. Move the constant term to the right: Add '-21' to each side of the equation. 21 + 6x + -21 + x2 = 0 + -21 Reorder the terms: 21 + -21 + 6x + x2 = 0 + -21 Combine like terms: 21 + -21 = 0 0 + 6x + x2 = 0 + -21 6x + x2 = 0 + -21 Combine like terms: 0 + -21 = -21 6x + x2 = -21 The x term is 6x. Take half its coefficient (3). Square it (9) and add it to both sides. Add '9' to each side of the equation. 6x + 9 + x2 = -21 + 9 Reorder the terms: 9 + 6x + x2 = -21 + 9 Combine like terms: -21 + 9 = -12 9 + 6x + x2 = -12 Factor a perfect square on the left side: (x + 3)(x + 3) = -12 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. The solution to this equation could not be determined.
