Simplifying 4x2 + 84x + 1120 = 0 Reorder the terms: 1120 + 84x + 4x2 = 0 Solving 1120 + 84x + 4x2 = 0 Solving for variable 'x'. Factor out the Greatest Common Factor (GCF), '4'. 4(280 + 21x + x2) = 0 Ignore the factor 4.Subproblem 1
Set the factor '(280 + 21x + x2)' equal to zero and attempt to solve: Simplifying 280 + 21x + x2 = 0 Solving 280 + 21x + x2 = 0 Begin completing the square. Move the constant term to the right: Add '-280' to each side of the equation. 280 + 21x + -280 + x2 = 0 + -280 Reorder the terms: 280 + -280 + 21x + x2 = 0 + -280 Combine like terms: 280 + -280 = 0 0 + 21x + x2 = 0 + -280 21x + x2 = 0 + -280 Combine like terms: 0 + -280 = -280 21x + x2 = -280 The x term is 21x. Take half its coefficient (10.5). Square it (110.25) and add it to both sides. Add '110.25' to each side of the equation. 21x + 110.25 + x2 = -280 + 110.25 Reorder the terms: 110.25 + 21x + x2 = -280 + 110.25 Combine like terms: -280 + 110.25 = -169.75 110.25 + 21x + x2 = -169.75 Factor a perfect square on the left side: (x + 10.5)(x + 10.5) = -169.75 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.
