Simplifying 0 = -16x2 + 64x + 5 Reorder the terms: 0 = 5 + 64x + -16x2 Solving 0 = 5 + 64x + -16x2 Solving for variable 'x'. Combine like terms: 0 + -5 = -5 -5 + -64x + 16x2 = 5 + 64x + -16x2 + -5 + -64x + 16x2 Reorder the terms: -5 + -64x + 16x2 = 5 + -5 + 64x + -64x + -16x2 + 16x2 Combine like terms: 5 + -5 = 0 -5 + -64x + 16x2 = 0 + 64x + -64x + -16x2 + 16x2 -5 + -64x + 16x2 = 64x + -64x + -16x2 + 16x2 Combine like terms: 64x + -64x = 0 -5 + -64x + 16x2 = 0 + -16x2 + 16x2 -5 + -64x + 16x2 = -16x2 + 16x2 Combine like terms: -16x2 + 16x2 = 0 -5 + -64x + 16x2 = 0 Begin completing the square. Divide all terms by 16 the coefficient of the squared term: Divide each side by '16'. -0.3125 + -4x + x2 = 0 Move the constant term to the right: Add '0.3125' to each side of the equation. -0.3125 + -4x + 0.3125 + x2 = 0 + 0.3125 Reorder the terms: -0.3125 + 0.3125 + -4x + x2 = 0 + 0.3125 Combine like terms: -0.3125 + 0.3125 = 0.0000 0.0000 + -4x + x2 = 0 + 0.3125 -4x + x2 = 0 + 0.3125 Combine like terms: 0 + 0.3125 = 0.3125 -4x + x2 = 0.3125 The x term is -4x. Take half its coefficient (-2). Square it (4) and add it to both sides. Add '4' to each side of the equation. -4x + 4 + x2 = 0.3125 + 4 Reorder the terms: 4 + -4x + x2 = 0.3125 + 4 Combine like terms: 0.3125 + 4 = 4.3125 4 + -4x + x2 = 4.3125 Factor a perfect square on the left side: (x + -2)(x + -2) = 4.3125 Calculate the square root of the right side: 2.076655966 Break this problem into two subproblems by setting (x + -2) equal to 2.076655966 and -2.076655966.Subproblem 1
x + -2 = 2.076655966 Simplifying x + -2 = 2.076655966 Reorder the terms: -2 + x = 2.076655966 Solving -2 + x = 2.076655966 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right.
