Simplifying 2x2 + 16x + -9 = 0 Reorder the terms: -9 + 16x + 2x2 = 0 Solving -9 + 16x + 2x2 = 0 Solving for variable 'x'. Begin completing the square. Divide all terms by 2 the coefficient of the squared term: Divide each side by '2'. -4.5 + 8x + x2 = 0 Move the constant term to the right: Add '4.5' to each side of the equation. -4.5 + 8x + 4.5 + x2 = 0 + 4.5 Reorder the terms: -4.5 + 4.5 + 8x + x2 = 0 + 4.5 Combine like terms: -4.5 + 4.5 = 0.0 0.0 + 8x + x2 = 0 + 4.5 8x + x2 = 0 + 4.5 Combine like terms: 0 + 4.5 = 4.5 8x + x2 = 4.5 The x term is 8x. Take half its coefficient (4). Square it (16) and add it to both sides. Add '16' to each side of the equation. 8x + 16 + x2 = 4.5 + 16 Reorder the terms: 16 + 8x + x2 = 4.5 + 16 Combine like terms: 4.5 + 16 = 20.5 16 + 8x + x2 = 20.5 Factor a perfect square on the left side: (x + 4)(x + 4) = 20.5 Calculate the square root of the right side: 4.527692569 Break this problem into two subproblems by setting (x + 4) equal to 4.527692569 and -4.527692569.Subproblem 1
x + 4 = 4.527692569 Simplifying x + 4 = 4.527692569 Reorder the terms: 4 + x = 4.527692569 Solving 4 + x = 4.527692569 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-4' to each side of the equation. 4 + -4 + x = 4.527692569 + -4 Combine like terms: 4 + -4 = 0 0 + x = 4.527692569 + -4 x = 4.527692569 + -4 Combine like terms: 4.527692569 + -4 = 0.527692569 x = 0.527692569 Simplifying x = 0.527692569Subproblem 2
x + 4 = -4.527692569 Simplifying x + 4 = -4.527692569 Reorder the terms: 4 + x = -4.527692569 Solving 4 + x = -4.527692569 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-4' to each side of the equation. 4 + -4 + x = -4.527692569 + -4 Combine like terms: 4 + -4 = 0 0 + x = -4.527692569 + -4 x = -4.527692569 + -4 Combine like terms: -4.527692569 + -4 = -8.527692569 x = -8.527692569 Simplifying x = -8.527692569Solution
