Simplifying 38 + -8x + x2 = 0 Solving 38 + -8x + x2 = 0 Solving for variable 'x'. Begin completing the square. Move the constant term to the right: Add '-38' to each side of the equation. 38 + -8x + -38 + x2 = 0 + -38 Reorder the terms: 38 + -38 + -8x + x2 = 0 + -38 Combine like terms: 38 + -38 = 0 0 + -8x + x2 = 0 + -38 -8x + x2 = 0 + -38 Combine like terms: 0 + -38 = -38 -8x + x2 = -38 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 = -38 + 16 Reorder the terms: 16 + -8x + x2 = -38 + 16 Combine like terms: -38 + 16 = -22 16 + -8x + x2 = -22 Factor a perfect square on the left side: (x + -4)(x + -4) = -22 Can't calculate square root of the right side. The solution to this equation could not be determined.
