Simplifying a2 + -4a = -16 Reorder the terms: -4a + a2 = -16 Solving -4a + a2 = -16 Solving for variable 'a'. Reorder the terms: 16 + -4a + a2 = -16 + 16 Combine like terms: -16 + 16 = 0 16 + -4a + a2 = 0 Begin completing the square. Move the constant term to the right: Add '-16' to each side of the equation. 16 + -4a + -16 + a2 = 0 + -16 Reorder the terms: 16 + -16 + -4a + a2 = 0 + -16 Combine like terms: 16 + -16 = 0 0 + -4a + a2 = 0 + -16 -4a + a2 = 0 + -16 Combine like terms: 0 + -16 = -16 -4a + a2 = -16 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 = -16 + 4 Reorder the terms: 4 + -4a + a2 = -16 + 4 Combine like terms: -16 + 4 = -12 4 + -4a + a2 = -12 Factor a perfect square on the left side: (a + -2)(a + -2) = -12 Can't calculate square root of the right side. The solution to this equation could not be determined.
