Simplifying X2 + -14X + 50 = 0 Reorder the terms: 50 + -14X + X2 = 0 Solving 50 + -14X + X2 = 0 Solving for variable 'X'. Begin completing the square. Move the constant term to the right: Add '-50' to each side of the equation. 50 + -14X + -50 + X2 = 0 + -50 Reorder the terms: 50 + -50 + -14X + X2 = 0 + -50 Combine like terms: 50 + -50 = 0 0 + -14X + X2 = 0 + -50 -14X + X2 = 0 + -50 Combine like terms: 0 + -50 = -50 -14X + X2 = -50 The X term is -14X. Take half its coefficient (-7). Square it (49) and add it to both sides. Add '49' to each side of the equation. -14X + 49 + X2 = -50 + 49 Reorder the terms: 49 + -14X + X2 = -50 + 49 Combine like terms: -50 + 49 = -1 49 + -14X + X2 = -1 Factor a perfect square on the left side: (X + -7)(X + -7) = -1 Can't calculate square root of the right side. The solution to this equation could not be determined.
