Simplifying 16 = 9x + -2x2 Solving 16 = 9x + -2x2 Solving for variable 'x'. Reorder the terms: 16 + -9x + 2x2 = 9x + -9x + -2x2 + 2x2 Combine like terms: 9x + -9x = 0 16 + -9x + 2x2 = 0 + -2x2 + 2x2 16 + -9x + 2x2 = -2x2 + 2x2 Combine like terms: -2x2 + 2x2 = 0 16 + -9x + 2x2 = 0 Begin completing the square. Divide all terms by 2 the coefficient of the squared term: Divide each side by '2'. 8 + -4.5x + x2 = 0 Move the constant term to the right: Add '-8' to each side of the equation. 8 + -4.5x + -8 + x2 = 0 + -8 Reorder the terms: 8 + -8 + -4.5x + x2 = 0 + -8 Combine like terms: 8 + -8 = 0 0 + -4.5x + x2 = 0 + -8 -4.5x + x2 = 0 + -8 Combine like terms: 0 + -8 = -8 -4.5x + x2 = -8 The x term is -4.5x. Take half its coefficient (-2.25). Square it (5.0625) and add it to both sides. Add '5.0625' to each side of the equation. -4.5x + 5.0625 + x2 = -8 + 5.0625 Reorder the terms: 5.0625 + -4.5x + x2 = -8 + 5.0625 Combine like terms: -8 + 5.0625 = -2.9375 5.0625 + -4.5x + x2 = -2.9375 Factor a perfect square on the left side: (x + -2.25)(x + -2.25) = -2.9375 Can't calculate square root of the right side. The solution to this equation could not be determined.
