Simplifying x2 + -8x = -80 Reorder the terms: -8x + x2 = -80 Solving -8x + x2 = -80 Solving for variable 'x'. Reorder the terms: 80 + -8x + x2 = -80 + 80 Combine like terms: -80 + 80 = 0 80 + -8x + x2 = 0 Begin completing the square. Move the constant term to the right: Add '-80' to each side of the equation. 80 + -8x + -80 + x2 = 0 + -80 Reorder the terms: 80 + -80 + -8x + x2 = 0 + -80 Combine like terms: 80 + -80 = 0 0 + -8x + x2 = 0 + -80 -8x + x2 = 0 + -80 Combine like terms: 0 + -80 = -80 -8x + x2 = -80 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 = -80 + 16 Reorder the terms: 16 + -8x + x2 = -80 + 16 Combine like terms: -80 + 16 = -64 16 + -8x + x2 = -64 Factor a perfect square on the left side: (x + -4)(x + -4) = -64 Can't calculate square root of the right side. The solution to this equation could not be determined.
