Simplifying -15 + 1a = 2a2 Solving -15 + 1a = 2a2 Solving for variable 'a'. Combine like terms: 2a2 + -2a2 = 0 -15 + 1a + -2a2 = 0 Begin completing the square. Divide all terms by -2 the coefficient of the squared term: Divide each side by '-2'. 7.5 + -0.5a + a2 = 0 Move the constant term to the right: Add '-7.5' to each side of the equation. 7.5 + -0.5a + -7.5 + a2 = 0 + -7.5 Reorder the terms: 7.5 + -7.5 + -0.5a + a2 = 0 + -7.5 Combine like terms: 7.5 + -7.5 = 0.0 0.0 + -0.5a + a2 = 0 + -7.5 -0.5a + a2 = 0 + -7.5 Combine like terms: 0 + -7.5 = -7.5 -0.5a + a2 = -7.5 The a term is -0.5a. Take half its coefficient (-0.25). Square it (0.0625) and add it to both sides. Add '0.0625' to each side of the equation. -0.5a + 0.0625 + a2 = -7.5 + 0.0625 Reorder the terms: 0.0625 + -0.5a + a2 = -7.5 + 0.0625 Combine like terms: -7.5 + 0.0625 = -7.4375 0.0625 + -0.5a + a2 = -7.4375 Factor a perfect square on the left side: (a + -0.25)(a + -0.25) = -7.4375 Can't calculate square root of the right side. The solution to this equation could not be determined.
