Simplifying a2 + -4a + 15 = 0 Reorder the terms: 15 + -4a + a2 = 0 Solving 15 + -4a + a2 = 0 Solving for variable 'a'. Begin completing the square. Move the constant term to the right: Add '-15' to each side of the equation. 15 + -4a + -15 + a2 = 0 + -15 Reorder the terms: 15 + -15 + -4a + a2 = 0 + -15 Combine like terms: 15 + -15 = 0 0 + -4a + a2 = 0 + -15 -4a + a2 = 0 + -15 Combine like terms: 0 + -15 = -15 -4a + a2 = -15 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 = -15 + 4 Reorder the terms: 4 + -4a + a2 = -15 + 4 Combine like terms: -15 + 4 = -11 4 + -4a + a2 = -11 Factor a perfect square on the left side: (a + -2)(a + -2) = -11 Can't calculate square root of the right side. The solution to this equation could not be determined.
