Simplifying -16t2 + 7t + -4 = 0 Reorder the terms: -4 + 7t + -16t2 = 0 Solving -4 + 7t + -16t2 = 0 Solving for variable 't'. Begin completing the square. Divide all terms by -16 the coefficient of the squared term: Divide each side by '-16'. 0.25 + -0.4375t + t2 = 0 Move the constant term to the right: Add '-0.25' to each side of the equation. 0.25 + -0.4375t + -0.25 + t2 = 0 + -0.25 Reorder the terms: 0.25 + -0.25 + -0.4375t + t2 = 0 + -0.25 Combine like terms: 0.25 + -0.25 = 0.00 0.00 + -0.4375t + t2 = 0 + -0.25 -0.4375t + t2 = 0 + -0.25 Combine like terms: 0 + -0.25 = -0.25 -0.4375t + t2 = -0.25 The t term is -0.4375t. Take half its coefficient (-0.21875). Square it (0.0478515625) and add it to both sides. Add '0.0478515625' to each side of the equation. -0.4375t + 0.0478515625 + t2 = -0.25 + 0.0478515625 Reorder the terms: 0.0478515625 + -0.4375t + t2 = -0.25 + 0.0478515625 Combine like terms: -0.25 + 0.0478515625 = -0.2021484375 0.0478515625 + -0.4375t + t2 = -0.2021484375 Factor a perfect square on the left side: (t + -0.21875)(t + -0.21875) = -0.2021484375 Can't calculate square root of the right side. The solution to this equation could not be determined.
