Simplifying a2 + -25a + 16 = 0 Reorder the terms: 16 + -25a + a2 = 0 Solving 16 + -25a + a2 = 0 Solving for variable 'a'. Begin completing the square. Move the constant term to the right: Add '-16' to each side of the equation. 16 + -25a + -16 + a2 = 0 + -16 Reorder the terms: 16 + -16 + -25a + a2 = 0 + -16 Combine like terms: 16 + -16 = 0 0 + -25a + a2 = 0 + -16 -25a + a2 = 0 + -16 Combine like terms: 0 + -16 = -16 -25a + a2 = -16 The a term is -25a. Take half its coefficient (-12.5). Square it (156.25) and add it to both sides. Add '156.25' to each side of the equation. -25a + 156.25 + a2 = -16 + 156.25 Reorder the terms: 156.25 + -25a + a2 = -16 + 156.25 Combine like terms: -16 + 156.25 = 140.25 156.25 + -25a + a2 = 140.25 Factor a perfect square on the left side: (a + -12.5)(a + -12.5) = 140.25 Calculate the square root of the right side: 11.842719282 Break this problem into two subproblems by setting (a + -12.5) equal to 11.842719282 and -11.842719282.Subproblem 1
a + -12.5 = 11.842719282 Simplifying a + -12.5 = 11.842719282 Reorder the terms: -12.5 + a = 11.842719282 Solving -12.5 + a = 11.842719282 Solving for variable 'a'. Move all terms containing a to the left, all other terms to the right. Add '12.5' to each side of the equation. -12.5 + 12.5 + a = 11.842719282 + 12.5 Combine like terms: -12.5 + 12.5 = 0.0 0.0 + a = 11.842719282 + 12.5 a = 11.842719282 + 12.5 Combine like terms: 11.842719282 + 12.5 = 24.342719282 a = 24.342719282 Simplifying a = 24.342719282Subproblem 2
a + -12.5 = -11.842719282 Simplifying a + -12.5 = -11.842719282 Reorder the terms: -12.5 + a = -11.842719282 Solving -12.5 + a = -11.842719282 Solving for variable 'a'. Move all terms containing a to the left, all other terms to the right. Add '12.5' to each side of the equation. -12.5 + 12.5 + a = -11.842719282 + 12.5 Combine like terms: -12.5 + 12.5 = 0.0 0.0 + a = -11.842719282 + 12.5 a = -11.842719282 + 12.5 Combine like terms: -11.842719282 + 12.5 = 0.657280718 a = 0.657280718 Simplifying a = 0.657280718Solution
