Simplifying x2 + -8x + 20.8 = 0 Reorder the terms: 20.8 + -8x + x2 = 0 Solving 20.8 + -8x + x2 = 0 Solving for variable 'x'. Begin completing the square. Move the constant term to the right: Add '-20.8' to each side of the equation. 20.8 + -8x + -20.8 + x2 = 0 + -20.8 Reorder the terms: 20.8 + -20.8 + -8x + x2 = 0 + -20.8 Combine like terms: 20.8 + -20.8 = 0.0 0.0 + -8x + x2 = 0 + -20.8 -8x + x2 = 0 + -20.8 Combine like terms: 0 + -20.8 = -20.8 -8x + x2 = -20.8 The x term is -8x. Take half its coefficient (-4). Square it (16) and add it to both sides. Add '16' to each side of the equation. -8x + 16 + x2 = -20.8 + 16 Reorder the terms: 16 + -8x + x2 = -20.8 + 16 Combine like terms: -20.8 + 16 = -4.8 16 + -8x + x2 = -4.8 Factor a perfect square on the left side: (x + -4)(x + -4) = -4.8 Can't calculate square root of the right side. The solution to this equation could not be determined.
