Simplifying 25t2 + -20t + 7 = 0 Reorder the terms: 7 + -20t + 25t2 = 0 Solving 7 + -20t + 25t2 = 0 Solving for variable 't'. Begin completing the square. Divide all terms by 25 the coefficient of the squared term: Divide each side by '25'. 0.28 + -0.8t + t2 = 0 Move the constant term to the right: Add '-0.28' to each side of the equation. 0.28 + -0.8t + -0.28 + t2 = 0 + -0.28 Reorder the terms: 0.28 + -0.28 + -0.8t + t2 = 0 + -0.28 Combine like terms: 0.28 + -0.28 = 0.00 0.00 + -0.8t + t2 = 0 + -0.28 -0.8t + t2 = 0 + -0.28 Combine like terms: 0 + -0.28 = -0.28 -0.8t + t2 = -0.28 The t term is -0.8t. Take half its coefficient (-0.4). Square it (0.16) and add it to both sides. Add '0.16' to each side of the equation. -0.8t + 0.16 + t2 = -0.28 + 0.16 Reorder the terms: 0.16 + -0.8t + t2 = -0.28 + 0.16 Combine like terms: -0.28 + 0.16 = -0.12 0.16 + -0.8t + t2 = -0.12 Factor a perfect square on the left side: (t + -0.4)(t + -0.4) = -0.12 Can't calculate square root of the right side. The solution to this equation could not be determined.
