Simplifying 4x2 + 25x + 46 = 4x + 1 Reorder the terms: 46 + 25x + 4x2 = 4x + 1 Reorder the terms: 46 + 25x + 4x2 = 1 + 4x Solving 46 + 25x + 4x2 = 1 + 4x Solving for variable 'x'. Reorder the terms: 46 + -1 + 25x + -4x + 4x2 = 1 + 4x + -1 + -4x Combine like terms: 46 + -1 = 45 45 + 25x + -4x + 4x2 = 1 + 4x + -1 + -4x Combine like terms: 25x + -4x = 21x 45 + 21x + 4x2 = 1 + 4x + -1 + -4x Reorder the terms: 45 + 21x + 4x2 = 1 + -1 + 4x + -4x Combine like terms: 1 + -1 = 0 45 + 21x + 4x2 = 0 + 4x + -4x 45 + 21x + 4x2 = 4x + -4x Combine like terms: 4x + -4x = 0 45 + 21x + 4x2 = 0 Begin completing the square. Divide all terms by 4 the coefficient of the squared term: Divide each side by '4'. 11.25 + 5.25x + x2 = 0 Move the constant term to the right: Add '-11.25' to each side of the equation. 11.25 + 5.25x + -11.25 + x2 = 0 + -11.25 Reorder the terms: 11.25 + -11.25 + 5.25x + x2 = 0 + -11.25 Combine like terms: 11.25 + -11.25 = 0.00 0.00 + 5.25x + x2 = 0 + -11.25 5.25x + x2 = 0 + -11.25 Combine like terms: 0 + -11.25 = -11.25 5.25x + x2 = -11.25 The x term is 5.25x. Take half its coefficient (2.625). Square it (6.890625) and add it to both sides. Add '6.890625' to each side of the equation. 5.25x + 6.890625 + x2 = -11.25 + 6.890625 Reorder the terms: 6.890625 + 5.25x + x2 = -11.25 + 6.890625 Combine like terms: -11.25 + 6.890625 = -4.359375 6.890625 + 5.25x + x2 = -4.359375 Factor a perfect square on the left side: (x + 2.625)(x + 2.625) = -4.359375 Can't calculate square root of the right side. The solution to this equation could not be determined.
