Simplifying -16t2 + 33t + -18 = 0 Reorder the terms: -18 + 33t + -16t2 = 0 Solving -18 + 33t + -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'. 1.125 + -2.0625t + t2 = 0 Move the constant term to the right: Add '-1.125' to each side of the equation. 1.125 + -2.0625t + -1.125 + t2 = 0 + -1.125 Reorder the terms: 1.125 + -1.125 + -2.0625t + t2 = 0 + -1.125 Combine like terms: 1.125 + -1.125 = 0.000 0.000 + -2.0625t + t2 = 0 + -1.125 -2.0625t + t2 = 0 + -1.125 Combine like terms: 0 + -1.125 = -1.125 -2.0625t + t2 = -1.125 The t term is -2.0625t. Take half its coefficient (-1.03125). Square it (1.063476563) and add it to both sides. Add '1.063476563' to each side of the equation. -2.0625t + 1.063476563 + t2 = -1.125 + 1.063476563 Reorder the terms: 1.063476563 + -2.0625t + t2 = -1.125 + 1.063476563 Combine like terms: -1.125 + 1.063476563 = -0.061523437 1.063476563 + -2.0625t + t2 = -0.061523437 Factor a perfect square on the left side: (t + -1.03125)(t + -1.03125) = -0.061523437 Can't calculate square root of the right side. The solution to this equation could not be determined.
