Simplifying 25x2 + -11x + 210 = 0 Reorder the terms: 210 + -11x + 25x2 = 0 Solving 210 + -11x + 25x2 = 0 Solving for variable 'x'. Begin completing the square. Divide all terms by 25 the coefficient of the squared term: Divide each side by '25'. 8.4 + -0.44x + x2 = 0 Move the constant term to the right: Add '-8.4' to each side of the equation. 8.4 + -0.44x + -8.4 + x2 = 0 + -8.4 Reorder the terms: 8.4 + -8.4 + -0.44x + x2 = 0 + -8.4 Combine like terms: 8.4 + -8.4 = 0.0 0.0 + -0.44x + x2 = 0 + -8.4 -0.44x + x2 = 0 + -8.4 Combine like terms: 0 + -8.4 = -8.4 -0.44x + x2 = -8.4 The x term is -0.44x. Take half its coefficient (-0.22). Square it (0.0484) and add it to both sides. Add '0.0484' to each side of the equation. -0.44x + 0.0484 + x2 = -8.4 + 0.0484 Reorder the terms: 0.0484 + -0.44x + x2 = -8.4 + 0.0484 Combine like terms: -8.4 + 0.0484 = -8.3516 0.0484 + -0.44x + x2 = -8.3516 Factor a perfect square on the left side: (x + -0.22)(x + -0.22) = -8.3516 Can't calculate square root of the right side. The solution to this equation could not be determined.
