Simplifying a(a + -3) = (a + 5) + -1(a + 2) Reorder the terms: a(-3 + a) = (a + 5) + -1(a + 2) (-3 * a + a * a) = (a + 5) + -1(a + 2) (-3a + a2) = (a + 5) + -1(a + 2) Reorder the terms: -3a + a2 = (5 + a) + -1(a + 2) Remove parenthesis around (5 + a) -3a + a2 = 5 + a + -1(a + 2) Reorder the terms: -3a + a2 = 5 + a + -1(2 + a) -3a + a2 = 5 + a + (2 * -1 + a * -1) -3a + a2 = 5 + a + (-2 + -1a) Reorder the terms: -3a + a2 = 5 + -2 + a + -1a Combine like terms: 5 + -2 = 3 -3a + a2 = 3 + a + -1a Combine like terms: a + -1a = 0 -3a + a2 = 3 + 0 -3a + a2 = 3 Solving -3a + a2 = 3 Solving for variable 'a'. Reorder the terms: -3 + -3a + a2 = 3 + -3 Combine like terms: 3 + -3 = 0 -3 + -3a + a2 = 0 Begin completing the square. Move the constant term to the right: Add '3' to each side of the equation. -3 + -3a + 3 + a2 = 0 + 3 Reorder the terms: -3 + 3 + -3a + a2 = 0 + 3 Combine like terms: -3 + 3 = 0 0 + -3a + a2 = 0 + 3 -3a + a2 = 0 + 3 Combine like terms: 0 + 3 = 3 -3a + a2 = 3 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 + 2.25 Reorder the terms: 2.25 + -3a + a2 = 3 + 2.25 Combine like terms: 3 + 2.25 = 5.25 2.25 + -3a + a2 = 5.25 Factor a perfect square on the left side: (a + -1.5)(a + -1.5) = 5.25 Calculate the square root of the right side: 2.291287847 Break this problem into two subproblems by setting (a + -1.5) equal to 2.291287847 and -2.291287847.Subproblem 1
a + -1.5 = 2.291287847 Simplifying a + -1.5 = 2.291287847 Reorder the terms: -1.5 + a = 2.291287847 Solving -1.5 + a = 2.291287847 Solving for variable 'a'. Move all terms containing a to the left, all other terms to the right. Add '1.5' to each side of the equation. -1.5 + 1.5 + a = 2.291287847 + 1.5 Combine like terms: -1.5 + 1.5 = 0.0 0.0 + a = 2.291287847 + 1.5 a = 2.291287847 + 1.5 Combine like terms: 2.291287847 + 1.5 = 3.791287847 a = 3.791287847 Simplifying a = 3.791287847Subproblem 2
a + -1.5 = -2.291287847 Simplifying a + -1.5 = -2.291287847 Reorder the terms: -1.5 + a = -2.291287847 Solving -1.5 + a = -2.291287847 Solving for variable 'a'. Move all terms containing a to the left, all other terms to the right. Add '1.5' to each side of the equation. -1.5 + 1.5 + a = -2.291287847 + 1.5 Combine like terms: -1.5 + 1.5 = 0.0 0.0 + a = -2.291287847 + 1.5 a = -2.291287847 + 1.5 Combine like terms: -2.291287847 + 1.5 = -0.791287847 a = -0.791287847 Simplifying a = -0.791287847Solution
The solution to the problem is based on the solutions from the subproblems. a = {3.791287847, -0.791287847}
