Simplifying 3a + 1 = -3.6a(a + -1) Reorder the terms: 1 + 3a = -3.6a(a + -1) Reorder the terms: 1 + 3a = -3.6a(-1 + a) 1 + 3a = (-1 * -3.6a + a * -3.6a) 1 + 3a = (3.6a + -3.6a2) Solving 1 + 3a = 3.6a + -3.6a2 Solving for variable 'a'. Combine like terms: 3a + -3.6a = -0.6a 1 + -0.6a + 3.6a2 = 3.6a + -3.6a2 + -3.6a + 3.6a2 Reorder the terms: 1 + -0.6a + 3.6a2 = 3.6a + -3.6a + -3.6a2 + 3.6a2 Combine like terms: 3.6a + -3.6a = 0.0 1 + -0.6a + 3.6a2 = 0.0 + -3.6a2 + 3.6a2 1 + -0.6a + 3.6a2 = -3.6a2 + 3.6a2 Combine like terms: -3.6a2 + 3.6a2 = 0.0 1 + -0.6a + 3.6a2 = 0.0 Begin completing the square. Divide all terms by 3.6 the coefficient of the squared term: Divide each side by '3.6'. 0.2777777778 + -0.1666666667a + a2 = 0 Move the constant term to the right: Add '-0.2777777778' to each side of the equation. 0.2777777778 + -0.1666666667a + -0.2777777778 + a2 = 0 + -0.2777777778 Reorder the terms: 0.2777777778 + -0.2777777778 + -0.1666666667a + a2 = 0 + -0.2777777778 Combine like terms: 0.2777777778 + -0.2777777778 = 0.0000000000 0.0000000000 + -0.1666666667a + a2 = 0 + -0.2777777778 -0.1666666667a + a2 = 0 + -0.2777777778 Combine like terms: 0 + -0.2777777778 = -0.2777777778 -0.1666666667a + a2 = -0.2777777778 The a term is -0.1666666667a. Take half its coefficient (-0.08333333335). Square it (0.006944444447) and add it to both sides. Add '0.006944444447' to each side of the equation. -0.1666666667a + 0.006944444447 + a2 = -0.2777777778 + 0.006944444447 Reorder the terms: 0.006944444447 + -0.1666666667a + a2 = -0.2777777778 + 0.006944444447 Combine like terms: -0.2777777778 + 0.006944444447 = -0.270833333353 0.006944444447 + -0.1666666667a + a2 = -0.270833333353 Factor a perfect square on the left side: (a + -0.08333333335)(a + -0.08333333335) = -0.270833333353 Can't calculate square root of the right side. The solution to this equation could not be determined.
