Simplifying -4x2 + 25x + -45 = 0 Reorder the terms: -45 + 25x + -4x2 = 0 Solving -45 + 25x + -4x2 = 0 Solving for variable 'x'. Begin completing the square. Divide all terms by -4 the coefficient of the squared term: Divide each side by '-4'. 11.25 + -6.25x + x2 = 0 Move the constant term to the right: Add '-11.25' to each side of the equation. 11.25 + -6.25x + -11.25 + x2 = 0 + -11.25 Reorder the terms: 11.25 + -11.25 + -6.25x + x2 = 0 + -11.25 Combine like terms: 11.25 + -11.25 = 0.00 0.00 + -6.25x + x2 = 0 + -11.25 -6.25x + x2 = 0 + -11.25 Combine like terms: 0 + -11.25 = -11.25 -6.25x + x2 = -11.25 The x term is -6.25x. Take half its coefficient (-3.125). Square it (9.765625) and add it to both sides. Add '9.765625' to each side of the equation. -6.25x + 9.765625 + x2 = -11.25 + 9.765625 Reorder the terms: 9.765625 + -6.25x + x2 = -11.25 + 9.765625 Combine like terms: -11.25 + 9.765625 = -1.484375 9.765625 + -6.25x + x2 = -1.484375 Factor a perfect square on the left side: (x + -3.125)(x + -3.125) = -1.484375 Can't calculate square root of the right side. The solution to this equation could not be determined.
