Simplifying 16x2 + 49 = x Reorder the terms: 49 + 16x2 = x Solving 49 + 16x2 = x Solving for variable 'x'. Reorder the terms: 49 + -1x + 16x2 = x + -1x Combine like terms: x + -1x = 0 49 + -1x + 16x2 = 0 Begin completing the square. Divide all terms by 16 the coefficient of the squared term: Divide each side by '16'. 3.0625 + -0.0625x + x2 = 0 Move the constant term to the right: Add '-3.0625' to each side of the equation. 3.0625 + -0.0625x + -3.0625 + x2 = 0 + -3.0625 Reorder the terms: 3.0625 + -3.0625 + -0.0625x + x2 = 0 + -3.0625 Combine like terms: 3.0625 + -3.0625 = 0.0000 0.0000 + -0.0625x + x2 = 0 + -3.0625 -0.0625x + x2 = 0 + -3.0625 Combine like terms: 0 + -3.0625 = -3.0625 -0.0625x + x2 = -3.0625 The x term is -0.0625x. Take half its coefficient (-0.03125). Square it (0.0009765625) and add it to both sides. Add '0.0009765625' to each side of the equation. -0.0625x + 0.0009765625 + x2 = -3.0625 + 0.0009765625 Reorder the terms: 0.0009765625 + -0.0625x + x2 = -3.0625 + 0.0009765625 Combine like terms: -3.0625 + 0.0009765625 = -3.0615234375 0.0009765625 + -0.0625x + x2 = -3.0615234375 Factor a perfect square on the left side: (x + -0.03125)(x + -0.03125) = -3.0615234375 Can't calculate square root of the right side. The solution to this equation could not be determined.
