Simplifying 2x2 + 6x + 9 = 5x Reorder the terms: 9 + 6x + 2x2 = 5x Solving 9 + 6x + 2x2 = 5x Solving for variable 'x'. Reorder the terms: 9 + 6x + -5x + 2x2 = 5x + -5x Combine like terms: 6x + -5x = 1x 9 + 1x + 2x2 = 5x + -5x Combine like terms: 5x + -5x = 0 9 + 1x + 2x2 = 0 Begin completing the square. Divide all terms by 2 the coefficient of the squared term: Divide each side by '2'. 4.5 + 0.5x + x2 = 0 Move the constant term to the right: Add '-4.5' to each side of the equation. 4.5 + 0.5x + -4.5 + x2 = 0 + -4.5 Reorder the terms: 4.5 + -4.5 + 0.5x + x2 = 0 + -4.5 Combine like terms: 4.5 + -4.5 = 0.0 0.0 + 0.5x + x2 = 0 + -4.5 0.5x + x2 = 0 + -4.5 Combine like terms: 0 + -4.5 = -4.5 0.5x + x2 = -4.5 The x term is 0.5x. Take half its coefficient (0.25). Square it (0.0625) and add it to both sides. Add '0.0625' to each side of the equation. 0.5x + 0.0625 + x2 = -4.5 + 0.0625 Reorder the terms: 0.0625 + 0.5x + x2 = -4.5 + 0.0625 Combine like terms: -4.5 + 0.0625 = -4.4375 0.0625 + 0.5x + x2 = -4.4375 Factor a perfect square on the left side: (x + 0.25)(x + 0.25) = -4.4375 Can't calculate square root of the right side. The solution to this equation could not be determined.
