Simplifying x2 + -8x + 65 = 0 Reorder the terms: 65 + -8x + x2 = 0 Solving 65 + -8x + x2 = 0 Solving for variable 'x'. Begin completing the square. Move the constant term to the right: Add '-65' to each side of the equation. 65 + -8x + -65 + x2 = 0 + -65 Reorder the terms: 65 + -65 + -8x + x2 = 0 + -65 Combine like terms: 65 + -65 = 0 0 + -8x + x2 = 0 + -65 -8x + x2 = 0 + -65 Combine like terms: 0 + -65 = -65 -8x + x2 = -65 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 = -65 + 16 Reorder the terms: 16 + -8x + x2 = -65 + 16 Combine like terms: -65 + 16 = -49 16 + -8x + x2 = -49 Factor a perfect square on the left side: (x + -4)(x + -4) = -49 Can't calculate square root of the right side. The solution to this equation could not be determined.
