Simplifying -100a2 + 35a + -2.25 = 0 Reorder the terms: -2.25 + 35a + -100a2 = 0 Solving -2.25 + 35a + -100a2 = 0 Solving for variable 'a'. Begin completing the square. Divide all terms by -100 the coefficient of the squared term: Divide each side by '-100'. 0.0225 + -0.35a + a2 = 0 Move the constant term to the right: Add '-0.0225' to each side of the equation. 0.0225 + -0.35a + -0.0225 + a2 = 0 + -0.0225 Reorder the terms: 0.0225 + -0.0225 + -0.35a + a2 = 0 + -0.0225 Combine like terms: 0.0225 + -0.0225 = 0.0000 0.0000 + -0.35a + a2 = 0 + -0.0225 -0.35a + a2 = 0 + -0.0225 Combine like terms: 0 + -0.0225 = -0.0225 -0.35a + a2 = -0.0225 The a term is -0.35a. Take half its coefficient (-0.175). Square it (0.030625) and add it to both sides. Add '0.030625' to each side of the equation. -0.35a + 0.030625 + a2 = -0.0225 + 0.030625 Reorder the terms: 0.030625 + -0.35a + a2 = -0.0225 + 0.030625 Combine like terms: -0.0225 + 0.030625 = 0.008125 0.030625 + -0.35a + a2 = 0.008125 Factor a perfect square on the left side: (a + -0.175)(a + -0.175) = 0.008125 Calculate the square root of the right side: 0.090138782 Break this problem into two subproblems by setting (a + -0.175) equal to 0.090138782 and -0.090138782.Subproblem 1
a + -0.175 = 0.090138782 Simplifying a + -0.175 = 0.090138782 Reorder the terms: -0.175 + a = 0.090138782 Solving -0.175 + a = 0.090138782 Solving for variable 'a'. Move all terms containing a to the left, all other terms to the right. Add '0.175' to each side of the equation. -0.175 + 0.175 + a = 0.090138782 + 0.175 Combine like terms: -0.175 + 0.175 = 0.000 0.000 + a = 0.090138782 + 0.175 a = 0.090138782 + 0.175 Combine like terms: 0.090138782 + 0.175 = 0.265138782 a = 0.265138782 Simplifying a = 0.265138782Subproblem 2
a + -0.175 = -0.090138782 Simplifying a + -0.175 = -0.090138782 Reorder the terms: -0.175 + a = -0.090138782 Solving -0.175 + a = -0.090138782 Solving for variable 'a'. Move all terms containing a to the left, all other terms to the right. Add '0.175' to each side of the equation. -0.175 + 0.175 + a = -0.090138782 + 0.175 Combine like terms: -0.175 + 0.175 = 0.000 0.000 + a = -0.090138782 + 0.175 a = -0.090138782 + 0.175 Combine like terms: -0.090138782 + 0.175 = 0.084861218 a = 0.084861218 Simplifying a = 0.084861218Solution
