Simplifying 7a + -5a(a + -3) = 27 Reorder the terms: 7a + -5a(-3 + a) = 27 7a + (-3 * -5a + a * -5a) = 27 7a + (15a + -5a2) = 27 Combine like terms: 7a + 15a = 22a 22a + -5a2 = 27 Solving 22a + -5a2 = 27 Solving for variable 'a'. Reorder the terms: -27 + 22a + -5a2 = 27 + -27 Combine like terms: 27 + -27 = 0 -27 + 22a + -5a2 = 0 Begin completing the square. Divide all terms by -5 the coefficient of the squared term: Divide each side by '-5'. 5.4 + -4.4a + a2 = 0 Move the constant term to the right: Add '-5.4' to each side of the equation. 5.4 + -4.4a + -5.4 + a2 = 0 + -5.4 Reorder the terms: 5.4 + -5.4 + -4.4a + a2 = 0 + -5.4 Combine like terms: 5.4 + -5.4 = 0.0 0.0 + -4.4a + a2 = 0 + -5.4 -4.4a + a2 = 0 + -5.4 Combine like terms: 0 + -5.4 = -5.4 -4.4a + a2 = -5.4 The a term is -4.4a. Take half its coefficient (-2.2). Square it (4.84) and add it to both sides. Add '4.84' to each side of the equation. -4.4a + 4.84 + a2 = -5.4 + 4.84 Reorder the terms: 4.84 + -4.4a + a2 = -5.4 + 4.84 Combine like terms: -5.4 + 4.84 = -0.56 4.84 + -4.4a + a2 = -0.56 Factor a perfect square on the left side: (a + -2.2)(a + -2.2) = -0.56 Can't calculate square root of the right side. The solution to this equation could not be determined.
