Simplifying 2a2 + 5a + -3 + -5a2 + 4a + -7 = 0 Reorder the terms: -3 + -7 + 5a + 4a + 2a2 + -5a2 = 0 Combine like terms: -3 + -7 = -10 -10 + 5a + 4a + 2a2 + -5a2 = 0 Combine like terms: 5a + 4a = 9a -10 + 9a + 2a2 + -5a2 = 0 Combine like terms: 2a2 + -5a2 = -3a2 -10 + 9a + -3a2 = 0 Solving -10 + 9a + -3a2 = 0 Solving for variable 'a'. Begin completing the square. Divide all terms by -3 the coefficient of the squared term: Divide each side by '-3'. 3.333333333 + -3a + a2 = 0 Move the constant term to the right: Add '-3.333333333' to each side of the equation. 3.333333333 + -3a + -3.333333333 + a2 = 0 + -3.333333333 Reorder the terms: 3.333333333 + -3.333333333 + -3a + a2 = 0 + -3.333333333 Combine like terms: 3.333333333 + -3.333333333 = 0.000000000 0.000000000 + -3a + a2 = 0 + -3.333333333 -3a + a2 = 0 + -3.333333333 Combine like terms: 0 + -3.333333333 = -3.333333333 -3a + a2 = -3.333333333 The a term is -3a. Take half its coefficient (-1.5). Square it (2.25) and add it to both sides. Add '2.25' to each side of the equation. -3a + 2.25 + a2 = -3.333333333 + 2.25 Reorder the terms: 2.25 + -3a + a2 = -3.333333333 + 2.25 Combine like terms: -3.333333333 + 2.25 = -1.083333333 2.25 + -3a + a2 = -1.083333333 Factor a perfect square on the left side: (a + -1.5)(a + -1.5) = -1.083333333 Can't calculate square root of the right side. The solution to this equation could not be determined.
