Simplifying 16t2 + 8t + 224 = 0 Reorder the terms: 224 + 8t + 16t2 = 0 Solving 224 + 8t + 16t2 = 0 Solving for variable 't'. Factor out the Greatest Common Factor (GCF), '8'. 8(28 + t + 2t2) = 0 Ignore the factor 8.Subproblem 1
Set the factor '(28 + t + 2t2)' equal to zero and attempt to solve: Simplifying 28 + t + 2t2 = 0 Solving 28 + t + 2t2 = 0 Begin completing the square. Divide all terms by 2 the coefficient of the squared term: Divide each side by '2'. 14 + 0.5t + t2 = 0 Move the constant term to the right: Add '-14' to each side of the equation. 14 + 0.5t + -14 + t2 = 0 + -14 Reorder the terms: 14 + -14 + 0.5t + t2 = 0 + -14 Combine like terms: 14 + -14 = 0 0 + 0.5t + t2 = 0 + -14 0.5t + t2 = 0 + -14 Combine like terms: 0 + -14 = -14 0.5t + t2 = -14 The t term is t. Take half its coefficient (0.5). Square it (0.25) and add it to both sides. Add '0.25' to each side of the equation. 0.5t + 0.25 + t2 = -14 + 0.25 Reorder the terms: 0.25 + 0.5t + t2 = -14 + 0.25 Combine like terms: -14 + 0.25 = -13.75 0.25 + 0.5t + t2 = -13.75 Factor a perfect square on the left side: (t + 0.5)(t + 0.5) = -13.75 Can't calculate square root of the right side.
