Simplifying a2 + 4a + 10 = 0 Reorder the terms: 10 + 4a + a2 = 0 Solving 10 + 4a + a2 = 0 Solving for variable 'a'. Begin completing the square. Move the constant term to the right: Add '-10' to each side of the equation. 10 + 4a + -10 + a2 = 0 + -10 Reorder the terms: 10 + -10 + 4a + a2 = 0 + -10 Combine like terms: 10 + -10 = 0 0 + 4a + a2 = 0 + -10 4a + a2 = 0 + -10 Combine like terms: 0 + -10 = -10 4a + a2 = -10 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 = -10 + 4 Reorder the terms: 4 + 4a + a2 = -10 + 4 Combine like terms: -10 + 4 = -6 4 + 4a + a2 = -6 Factor a perfect square on the left side: (a + 2)(a + 2) = -6 Can't calculate square root of the right side. The solution to this equation could not be determined.
