Simplifying x2 + -8x + 16 = -4 Reorder the terms: 16 + -8x + x2 = -4 Solving 16 + -8x + x2 = -4 Solving for variable 'x'. Reorder the terms: 16 + 4 + -8x + x2 = -4 + 4 Combine like terms: 16 + 4 = 20 20 + -8x + x2 = -4 + 4 Combine like terms: -4 + 4 = 0 20 + -8x + x2 = 0 Begin completing the square. Move the constant term to the right: Add '-20' to each side of the equation. 20 + -8x + -20 + x2 = 0 + -20 Reorder the terms: 20 + -20 + -8x + x2 = 0 + -20 Combine like terms: 20 + -20 = 0 0 + -8x + x2 = 0 + -20 -8x + x2 = 0 + -20 Combine like terms: 0 + -20 = -20 -8x + x2 = -20 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 + 16 Reorder the terms: 16 + -8x + x2 = -20 + 16 Combine like terms: -20 + 16 = -4 16 + -8x + x2 = -4 Factor a perfect square on the left side: (x + -4)(x + -4) = -4 Can't calculate square root of the right side. The solution to this equation could not be determined.
