Simplifying x2 + -3x + 168 = 0 Reorder the terms: 168 + -3x + x2 = 0 Solving 168 + -3x + x2 = 0 Solving for variable 'x'. Begin completing the square. Move the constant term to the right: Add '-168' to each side of the equation. 168 + -3x + -168 + x2 = 0 + -168 Reorder the terms: 168 + -168 + -3x + x2 = 0 + -168 Combine like terms: 168 + -168 = 0 0 + -3x + x2 = 0 + -168 -3x + x2 = 0 + -168 Combine like terms: 0 + -168 = -168 -3x + x2 = -168 The x term is -3x. Take half its coefficient (-1.5). Square it (2.25) and add it to both sides. Add '2.25' to each side of the equation. -3x + 2.25 + x2 = -168 + 2.25 Reorder the terms: 2.25 + -3x + x2 = -168 + 2.25 Combine like terms: -168 + 2.25 = -165.75 2.25 + -3x + x2 = -165.75 Factor a perfect square on the left side: (x + -1.5)(x + -1.5) = -165.75 Can't calculate square root of the right side. The solution to this equation could not be determined.
