Simplifying a2 + -4a + 12 = 0 Reorder the terms: 12 + -4a + a2 = 0 Solving 12 + -4a + a2 = 0 Solving for variable 'a'. Begin completing the square. Move the constant term to the right: Add '-12' to each side of the equation. 12 + -4a + -12 + a2 = 0 + -12 Reorder the terms: 12 + -12 + -4a + a2 = 0 + -12 Combine like terms: 12 + -12 = 0 0 + -4a + a2 = 0 + -12 -4a + a2 = 0 + -12 Combine like terms: 0 + -12 = -12 -4a + a2 = -12 The a term is -4a. Take half its coefficient (-2). Square it (4) and add it to both sides. Add '4' to each side of the equation. -4a + 4 + a2 = -12 + 4 Reorder the terms: 4 + -4a + a2 = -12 + 4 Combine like terms: -12 + 4 = -8 4 + -4a + a2 = -8 Factor a perfect square on the left side: (a + -2)(a + -2) = -8 Can't calculate square root of the right side. The solution to this equation could not be determined.
