Simplifying 2a2 + -10a = 21 Reorder the terms: -10a + 2a2 = 21 Solving -10a + 2a2 = 21 Solving for variable 'a'. Reorder the terms: -21 + -10a + 2a2 = 21 + -21 Combine like terms: 21 + -21 = 0 -21 + -10a + 2a2 = 0 Begin completing the square. Divide all terms by 2 the coefficient of the squared term: Divide each side by '2'. -10.5 + -5a + a2 = 0 Move the constant term to the right: Add '10.5' to each side of the equation. -10.5 + -5a + 10.5 + a2 = 0 + 10.5 Reorder the terms: -10.5 + 10.5 + -5a + a2 = 0 + 10.5 Combine like terms: -10.5 + 10.5 = 0.0 0.0 + -5a + a2 = 0 + 10.5 -5a + a2 = 0 + 10.5 Combine like terms: 0 + 10.5 = 10.5 -5a + a2 = 10.5 The a term is -5a. Take half its coefficient (-2.5). Square it (6.25) and add it to both sides. Add '6.25' to each side of the equation. -5a + 6.25 + a2 = 10.5 + 6.25 Reorder the terms: 6.25 + -5a + a2 = 10.5 + 6.25 Combine like terms: 10.5 + 6.25 = 16.75 6.25 + -5a + a2 = 16.75 Factor a perfect square on the left side: (a + -2.5)(a + -2.5) = 16.75 Calculate the square root of the right side: 4.092676386 Break this problem into two subproblems by setting (a + -2.5) equal to 4.092676386 and -4.092676386.Subproblem 1
a + -2.5 = 4.092676386 Simplifying a + -2.5 = 4.092676386 Reorder the terms: -2.5 + a = 4.092676386 Solving -2.5 + a = 4.092676386 Solving for variable 'a'. Move all terms containing a to the left, all other terms to the right. Add '2.5' to each side of the equation. -2.5 + 2.5 + a = 4.092676386 + 2.5 Combine like terms: -2.5 + 2.5 = 0.0 0.0 + a = 4.092676386 + 2.5 a = 4.092676386 + 2.5 Combine like terms: 4.092676386 + 2.5 = 6.592676386 a = 6.592676386 Simplifying a = 6.592676386Subproblem 2
a + -2.5 = -4.092676386 Simplifying a + -2.5 = -4.092676386 Reorder the terms: -2.5 + a = -4.092676386 Solving -2.5 + a = -4.092676386 Solving for variable 'a'. Move all terms containing a to the left, all other terms to the right. Add '2.5' to each side of the equation. -2.5 + 2.5 + a = -4.092676386 + 2.5 Combine like terms: -2.5 + 2.5 = 0.0 0.0 + a = -4.092676386 + 2.5 a = -4.092676386 + 2.5 Combine like terms: -4.092676386 + 2.5 = -1.592676386 a = -1.592676386 Simplifying a = -1.592676386Solution
