Simplifying a2 + -5a + 9 = 0 Reorder the terms: 9 + -5a + a2 = 0 Solving 9 + -5a + a2 = 0 Solving for variable 'a'. Begin completing the square. Move the constant term to the right: Add '-9' to each side of the equation. 9 + -5a + -9 + a2 = 0 + -9 Reorder the terms: 9 + -9 + -5a + a2 = 0 + -9 Combine like terms: 9 + -9 = 0 0 + -5a + a2 = 0 + -9 -5a + a2 = 0 + -9 Combine like terms: 0 + -9 = -9 -5a + a2 = -9 The a term is -5a. Take half its coefficient (-2.5). Square it (6.25) and add it to both sides. Add '6.25' to each side of the equation. -5a + 6.25 + a2 = -9 + 6.25 Reorder the terms: 6.25 + -5a + a2 = -9 + 6.25 Combine like terms: -9 + 6.25 = -2.75 6.25 + -5a + a2 = -2.75 Factor a perfect square on the left side: (a + -2.5)(a + -2.5) = -2.75 Can't calculate square root of the right side. The solution to this equation could not be determined.
