Simplifying 0 = x2 + 8x + -3 Reorder the terms: 0 = -3 + 8x + x2 Solving 0 = -3 + 8x + x2 Solving for variable 'x'. Combine like terms: 0 + 3 = 3 3 + -8x + -1x2 = -3 + 8x + x2 + 3 + -8x + -1x2 Reorder the terms: 3 + -8x + -1x2 = -3 + 3 + 8x + -8x + x2 + -1x2 Combine like terms: -3 + 3 = 0 3 + -8x + -1x2 = 0 + 8x + -8x + x2 + -1x2 3 + -8x + -1x2 = 8x + -8x + x2 + -1x2 Combine like terms: 8x + -8x = 0 3 + -8x + -1x2 = 0 + x2 + -1x2 3 + -8x + -1x2 = x2 + -1x2 Combine like terms: x2 + -1x2 = 0 3 + -8x + -1x2 = 0 Begin completing the square. Divide all terms by -1 the coefficient of the squared term: Divide each side by '-1'. -3 + 8x + x2 = 0 Move the constant term to the right: Add '3' to each side of the equation. -3 + 8x + 3 + x2 = 0 + 3 Reorder the terms: -3 + 3 + 8x + x2 = 0 + 3 Combine like terms: -3 + 3 = 0 0 + 8x + x2 = 0 + 3 8x + x2 = 0 + 3 Combine like terms: 0 + 3 = 3 8x + x2 = 3 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 = 3 + 16 Reorder the terms: 16 + 8x + x2 = 3 + 16 Combine like terms: 3 + 16 = 19 16 + 8x + x2 = 19 Factor a perfect square on the left side: (x + 4)(x + 4) = 19 Calculate the square root of the right side: 4.358898944 Break this problem into two subproblems by setting (x + 4) equal to 4.358898944 and -4.358898944.Subproblem 1
x + 4 = 4.358898944 Simplifying x + 4 = 4.358898944 Reorder the terms: 4 + x = 4.358898944 Solving 4 + x = 4.358898944 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 = 4.358898944 + -4 Combine like terms: 4 + -4 = 0 0 + x = 4.358898944 + -4 x = 4.358898944 + -4 Combine like terms: 4.358898944 + -4 = 0.358898944 x = 0.358898944 Simplifying x = 0.358898944Subproblem 2
x + 4 = -4.358898944 Simplifying x + 4 = -4.358898944 Reorder the terms: 4 + x = -4.358898944 Solving 4 + x = -4.358898944 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 = -4.358898944 + -4 Combine like terms: 4 + -4 = 0 0 + x = -4.358898944 + -4 x = -4.358898944 + -4 Combine like terms: -4.358898944 + -4 = -8.358898944 x = -8.358898944 Simplifying x = -8.358898944Solution
