Simplifying 4a2 + -13a + 5 = 0 Reorder the terms: 5 + -13a + 4a2 = 0 Solving 5 + -13a + 4a2 = 0 Solving for variable 'a'. Begin completing the square. Divide all terms by 4 the coefficient of the squared term: Divide each side by '4'. 1.25 + -3.25a + a2 = 0 Move the constant term to the right: Add '-1.25' to each side of the equation. 1.25 + -3.25a + -1.25 + a2 = 0 + -1.25 Reorder the terms: 1.25 + -1.25 + -3.25a + a2 = 0 + -1.25 Combine like terms: 1.25 + -1.25 = 0.00 0.00 + -3.25a + a2 = 0 + -1.25 -3.25a + a2 = 0 + -1.25 Combine like terms: 0 + -1.25 = -1.25 -3.25a + a2 = -1.25 The a term is -3.25a. Take half its coefficient (-1.625). Square it (2.640625) and add it to both sides. Add '2.640625' to each side of the equation. -3.25a + 2.640625 + a2 = -1.25 + 2.640625 Reorder the terms: 2.640625 + -3.25a + a2 = -1.25 + 2.640625 Combine like terms: -1.25 + 2.640625 = 1.390625 2.640625 + -3.25a + a2 = 1.390625 Factor a perfect square on the left side: (a + -1.625)(a + -1.625) = 1.390625 Calculate the square root of the right side: 1.179247642 Break this problem into two subproblems by setting (a + -1.625) equal to 1.179247642 and -1.179247642.Subproblem 1
a + -1.625 = 1.179247642 Simplifying a + -1.625 = 1.179247642 Reorder the terms: -1.625 + a = 1.179247642 Solving -1.625 + a = 1.179247642 Solving for variable 'a'. Move all terms containing a to the left, all other terms to the right. Add '1.625' to each side of the equation. -1.625 + 1.625 + a = 1.179247642 + 1.625 Combine like terms: -1.625 + 1.625 = 0.000 0.000 + a = 1.179247642 + 1.625 a = 1.179247642 + 1.625 Combine like terms: 1.179247642 + 1.625 = 2.804247642 a = 2.804247642 Simplifying a = 2.804247642Subproblem 2
a + -1.625 = -1.179247642 Simplifying a + -1.625 = -1.179247642 Reorder the terms: -1.625 + a = -1.179247642 Solving -1.625 + a = -1.179247642 Solving for variable 'a'. Move all terms containing a to the left, all other terms to the right. Add '1.625' to each side of the equation. -1.625 + 1.625 + a = -1.179247642 + 1.625 Combine like terms: -1.625 + 1.625 = 0.000 0.000 + a = -1.179247642 + 1.625 a = -1.179247642 + 1.625 Combine like terms: -1.179247642 + 1.625 = 0.445752358 a = 0.445752358 Simplifying a = 0.445752358Solution
