Simplifying x2 + -8x + 16 = -45 Reorder the terms: 16 + -8x + x2 = -45 Solving 16 + -8x + x2 = -45 Solving for variable 'x'. Reorder the terms: 16 + 45 + -8x + x2 = -45 + 45 Combine like terms: 16 + 45 = 61 61 + -8x + x2 = -45 + 45 Combine like terms: -45 + 45 = 0 61 + -8x + x2 = 0 Begin completing the square. Move the constant term to the right: Add '-61' to each side of the equation. 61 + -8x + -61 + x2 = 0 + -61 Reorder the terms: 61 + -61 + -8x + x2 = 0 + -61 Combine like terms: 61 + -61 = 0 0 + -8x + x2 = 0 + -61 -8x + x2 = 0 + -61 Combine like terms: 0 + -61 = -61 -8x + x2 = -61 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 = -61 + 16 Reorder the terms: 16 + -8x + x2 = -61 + 16 Combine like terms: -61 + 16 = -45 16 + -8x + x2 = -45 Factor a perfect square on the left side: (x + -4)(x + -4) = -45 Can't calculate square root of the right side. The solution to this equation could not be determined.
