Simplifying 6x + -1x2 = 64 Solving 6x + -1x2 = 64 Solving for variable 'x'. Reorder the terms: -64 + 6x + -1x2 = 64 + -64 Combine like terms: 64 + -64 = 0 -64 + 6x + -1x2 = 0 Begin completing the square. Divide all terms by -1 the coefficient of the squared term: Divide each side by '-1'. 64 + -6x + x2 = 0 Move the constant term to the right: Add '-64' to each side of the equation. 64 + -6x + -64 + x2 = 0 + -64 Reorder the terms: 64 + -64 + -6x + x2 = 0 + -64 Combine like terms: 64 + -64 = 0 0 + -6x + x2 = 0 + -64 -6x + x2 = 0 + -64 Combine like terms: 0 + -64 = -64 -6x + x2 = -64 The x term is -6x. Take half its coefficient (-3). Square it (9) and add it to both sides. Add '9' to each side of the equation. -6x + 9 + x2 = -64 + 9 Reorder the terms: 9 + -6x + x2 = -64 + 9 Combine like terms: -64 + 9 = -55 9 + -6x + x2 = -55 Factor a perfect square on the left side: (x + -3)(x + -3) = -55 Can't calculate square root of the right side. The solution to this equation could not be determined.
